Sequential actions of palladium and cobalt nanoparticles immobilized on silica: one-pot synthesis of bicyclic enones by catalytic allylic alkylation and Pauson-Khand …
... Organic Letters. ... Many transition-metal nanoparticles are highly active heterogeneous catalysts partly as a result of their high surface-to-volume ratio ... The annulation reaction was also applied to cyclization of chiral allylic carbonate II (Np = 2-naphthyl; Ts = 4-MeC6H4SO2) with HC ...
