Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. SDS of cas: 1055361-35-7, C19H11F3N2O4S.

Ultrasound assisted site-selective alkynylation of 2,3,5,6-tetrachloropyridines under Pd/C[sbnd]Cu catalysis
A convenient synthetic method has been developed for accessing 2,6-dialkynyl-3,5-dichloropyridine derivatives in acceptable to good yields. The methodology involved ultrasound assisted site-selective alkynylation of 2,3,5,6-tetrachloropyridines under Pd/C[sbnd]Cu catalysis. A variety of terminal alkynes were employed in this C[sbnd]C coupling reaction to afford the corresponding 2,6-dialkynyl-3,5-dichloropyridine derivatives.
