Reactions of Pentacarbonyl(trichloromethyl isocyanide)chromium

Abstract

A broad palette of organometallic compounds can be synthesized from the readily accessible 1, which exhibits two mutually reinforcing electrophilic centers, the isocyano unit and the halogenated α-C atom. The high synthetic potential of 1, as well as its 2-azaalleniumylidene and dichlorocarbene nature, are exemplified by preparation of 2–4.
