Mesoionic N-heterocyclic olefins have been developed, which feature high ylidic character. These compounds have been used as efficient catalysts for hydroboration of imines, nitriles, and N-heteroarenes.Article pubs.acs.org/joc

Synthesis and coordination of 4-halo-1,2,3-triazolylidenes have been developed.

The budding deuteriodifluoromethyl group (CF2D) is a potentially significant functional group in medicinal chemistry. Herein, we investigated t-BuOK-catalyzed H/D exchange reaction of difluoromethylarenes in DMSO-d 6 solution. The method provides excellent deuterium incorporation at the difluoromethyl group. Meanwhile, the effect of a trace amount of D2O in DMSO-d 6 solution on the deuteration reaction was also investigated.
