Co2(CO)8-Catalyzed Ring-Opening Carbonylation of Cyclic Ethers Using N-Silylamines

Article abstract of DOI:10.1246/bcsj.67.879

Co2(CO)8-catalyzed ring-opening carbonylation of oxiranes and oxetane smoothly proceeds with high regioselectivity under 1 atm of carbon monoxide at room temperature to give the corresponding β- and γ-siloxy amides in high yields, respectively. <(R3Si)2NR¹R²>^+- is thought to be an active catalyst species and directs the high regioselectivity of the carbonylation.
