B(C6F5)3-catalyzed metal-free hydrogenation of 3,6-diarylpyridazines

This paper describes the first metal-free hydrogenation of 3,6-diarylpyridazines, which was successfully realized using B(C6F5)3 as a catalyst. A variety of 1,4,5,6-tetrahydropyridazine derivatives were furnished in 85-95%

Successively recycle waste as catalyst: A one-pot wittig/1,4-reduction/paal-knorr sequence for modular synthesis of substituted furans

A one-pot tandem Wittig/conjugate reduction/Paal-Knorr reaction is reported for the synthesis of di- or trisubstituted furans. This novel sequence first demonstrates the possibility of successively recycling waste from upstream steps to catalyze downstream reactions.
