Synthesis and Reactivity of Cp2Zr(η2-C,N-CCH3)(1+). Regioselective Acetylation of Alkynes and Alkenes

Article abstract of DOI:10.1021/jo00073a011

The cationic iminoacyl species Cp2Zr(η²-C,N-C<=N-t-Bu>CH3)(1+), generated in situ from Cp2Zr(η²-C,N-C<=N-t-Bu>CH3)(CH3) and B(C6F5)3, inserts alkynes and alkenes to yield metallacycles which can be hydrolyzed to ketones in high overall yield.
