Trialkylphosphine for Morita-Baylis Hillman Reactions

The use of amines and phosphines in nucleophilic catalysis is well precedented; however, arguably one of the severe limitations with respect to exploiting the more nucleophilic, yet less basic, phosphine in this regard is its air sensitivity.

Catalysts for Carbonylation

Professor Geoffrey Coates and co-workers at Cornell University have reported the preparation and use of catalysts composed of an oxophilic Lewis acid and a cobalt tetracarbonyl anion for the ring expansive carbonylation of epoxides to b-lactones and b-lactones to succinic
