An unprecedented triple catalytic, general ring-opening cyanation reaction of cyclopropyl ketones for the construction of gamma-cyanoketones is described. The key is to merge photoredox catalysis with Lewis acid catalysis and copper catalysis to enable the selective cleavage of the carbon-carbon bonds and the selective coupling of the generated radical and cyanide anion.

The asymmetric Michael reaction of 3(2H) furanones and alpha, beta-unsaturated ketones was investigated, with the employment of a bulky chiral primary amine.

In spite of the fact that a variety of reactions have been exploited for creation of innumerable porous organic polymers (POPs), aldol condensation reactions between aldehydes and ketones leading to enones remain unutilized quite inexplicably. We surmised that the enone functionality can be exploited for stabilization of Pd akin to the manner of Pd(0) in Pd-2(dba)(3) by developing POPs based on aldol condensation reactions of polycarbonyl compounds with dialdehydes, and that such materials can be employed for catalytic transformations. By subjecting rationally designed tri-/tetraacetyl-functionalized aryl amines to aldol condensations with terephthalaldehyde, three different POPs, i.e., TPAPOPs 1-3, that feature enone functionalities have been synthesized and shown to exhibit palpable gas sorption properties. Remarkably, inverse uptake for sorption of H-2 over N-2 was observed for all POPs. As surmised, the representative POP, i.e., TPAPOP-1, was found to stabilize in situ-generated Pd(0) nanoparticles to enable application of the resultant material, i.e., Pd@TPAPOP-1, as a recyclable heterogeneous catalyst for a number of organic transformations. It is shown that coupling reactions such as Suzuki and Heck, and reductions such as nitro-to-amine and hydrogenation of olefins can be accomplished in a facile manner by employing Pd@TPAPOP-1 as a heterogeneous recyclable catalyst; the aforementioned transformations have been demonstrated on a broad set of substrates for each type.

A ruthenium(II)-catalyzed Michael addition ofN-acyl pyrroles to alpha,beta-unsaturated ketones has been developed by using a C-H activation strategy. The key to this selective reaction is to use an acyl group as an effective chelating group. The use of AgOTf remarkably promoted the protonolysis process and thereby facilitated the Michael addition reaction. Monoalkylated pyrroles could be selectively synthesized by controlling the ratio of alpha,beta-unsaturated ketones toN-acyl pyrroles.

A series of seven bis(pyridinedipyrrolide)zirconium complexes, Zr((PDPR2)-P-R1)(2), where [(PDPR2)-P-R1](2-) is the doubly deprotonated form of [2,6-bis(5-R-1-3-R-2-1H-pyrrol-2-yl)pyridine], were prepared and characterized in solution by NMR, UV/vis absorption, and emission spectroscopy and cyclic voltammetry. The molecular structures were determined by single-crystal X-ray crystallography. All complexes exhibit remarkably long emission lifetimes (tau = 190-576 mu s) with high quantum efficiencies (Phi(PL) = 0.10-0.38) upon excitation with visible light in a benzene solution. The substituents on the pyrrolide rings were shown to have significant effects on the photoluminescence and electrochemical properties of these compounds. The R-2 substituents (R-2 = H, Me, Ph, or C6F5) show only limited effects on the absorption and emission profiles of the complexes but allow systematic tuning of the ground- and excited-state redox potentials over a range of almost 600 mV. The R-1 substituents (R-1 = H, Me, Ph, or 2,4,6-Me3Ph) influence both the optical and electrochemical properties through electronic effects. Additionally, the R-1 substituents have profound consequences for the structural flexibility and overall stability of the compounds. Distortions of the Zr(PDP)(2) core from idealized D-2d symmetry in the solid state can be traced to the steric profiles of the R-1 substituents and correlate with the observed Stokes shifts for each compound. The complex with the smallest ligand system, Zr((PDPH)-P-H)(2), coordinates two additional solvent molecules in a tetrahydrofuran (THF) solution, which allowed the isolation of photoluminescent, eight-coordinate Zr((PDPH)-P-H)(2) (THF)(2). The photoredox catalytic dehalogenation of aryl iodides and aryl chlorides using the most reducing derivative, Zr((PDPMe)-P-Me)(2), highlights the potential of Zr(PDP)(2) photosensitizers to promote challenging reductive transformations under mild conditions upon excitation with green light.

The catalytic asymmetric epoxidation of alpha,beta-unsaturated ketones by tert-butylhydroperoxide (TBHP) has been well established using rare-earth metal amides RE[N(SiMe3)(2)](3) (RE = La(1), Nd(2), Sm(3), Y(4), Yb(5)) with chiral TADDOL ligands.

Various substrates were proved to have functional group tolerance. In addition, gram-level experiments and derivatization experiments were also studied.

The (Fmes)BH2 center dot SMe2 reagent (7) reacts sequentially with an acetylene and, e.g., xylylisonitrile in a convenient three-component reaction to give a series of unprecedented dihydro-1,3-azaborole derivatives 16. The tolane-derived example 16a was deprotonated and used as a ligand in organometallic chemistry. Compounds 16 served as the starting materials for the straightforward synthesis of various dihydro-1,3-azaborinine derivatives by treatment with an isonitrile. Several diaryldihydro-1,3 azaboroles showed interesting photophysical properties such as aggregation-induced emission and high fluorescence quantum yields.

C3-(Trans-2-arylethenyl)carbonylated chlorophyll derivatives possessing a bacteriochlorin or chlorin pi-system were synthesized by cross-aldol (Claisen-Schmidt) condensation of methyl pyrobacteriopheophorbide-a or 3-acetyl-3-devinyl-pyropheophorbide-a bearing the C3-acetyl group with p-(un)substituted benzaldehydes under basic conditions. The corresponding porphyrin-type chlorophyll derivatives were prepared by the oxidation (17,18-didehydrogenation) of the chlorin-type. Their Qy absorption and fluorescence emission maxima in dichloromethane correlated well with Hammett substituent constants of the p-substituents. Several electron-withdrawing p-substituents suppressed the emission due to photoinduced electron transfer quenching in a molecule. The substitution sensitivities for their maxima and fluorescence quantum yields decreased in the order of bacteriochlorin-, chlorin- and porphyrin-type derivatives.

We report the highly enantioselective synthesis of P-chiral tertiary phosphine oxides featuring an ethynyl group via Cu(i)-catalyzed azide-alkyne cycloaddition. Newly developed chiral pyridinebisoxazolines (PYBOX) bearing a bulky C4 shielding group play an important role in achieving excellent enantioselectivity while suppressing side bis-triazoles formation in desymmetrizing prochiral diethynylphosphine oxides. Notably, by tuning the size of the C4 shielding group, it is possible to achieve excellent remote enantiofacial control in desymmetrizing phosphole oxide-diynes with the prochiral P-center farther from the ethynyl group by four covalent bonds. Time-dependent enantioselectivity is observed for these desymmetric CuAAC reactions, suggesting a synergic combination of a desymmetrization and a kinetic resolution, and our ligands prove to be better than unmodified PYBOX in both steps. This finding contributes to a highly enantioselective kinetic resolution of racemic ethynylphosphine oxides. The resulting chiral ethynylphosphine oxides are versatile P-chiral synthons, which can undergo a number of diversifying reactions to enrich structural diversity.
