摘要

In this communication, we report general new methodology for the synthesis of substituted cyclobutanones, based on the highly selective mono-carbonylation of titanacyclobutane complexes, a new reactivity pattern for metallacyclobutane complexes of the early transition metals. In conjunction with the recent development of titanacyclobutane synthesis by free radical alkylation of η3-allyltitanium (III) complexes, 4 this carbonylation constitutes a ...
