Bismuth subnitrate is reported herein as a simple and efficient catalyst for the atom-economical synthesis of methyl ketones via Markovnikov-type alkyne hydration. Besides an effective batch process under reasonably mild conditions, chemically intensified continuous flow protocol was also developed in packed-bed system. The applicability methodologies demonstrated through hydration diverse set ...

The hydrosilylation of alkynes is one the most attractive and, at same time, challenging catalytic transformations, usually demanding use noble transition metals. We describe a system, based on cobalt(0) complex and bulky N-heterocyclic carbene (NHC) ligands, permitting highly effective broad scope silanes. application NHC ligands allowed decrease in amount cobalt necessary for an reaction run ...
