Insertion of Ketene and Diphenylketene to the Pnictogen-Heteroatom Bonds

Abstract

Abstract Ketene and diphenylketene insert across the heteroatom-metal bond of amino-, alkoxy-, and alkylthiopnictogens, R3−nMXn, to give the corresponding α-metallated acetamides, esters, and thioesters, R3−nM(CH2COX)n and R3−nM(CPh2COX)n (M=As, Sb, Bi; X=NR2, OR, SR; n=1,3), respectively.
