Cyclohexylidene carbene

Cyclohexylidene carbene and cyclopentylidene carbene have been generated by the base-induced decomposition of the appropriate 1 -(A-acety 1-jV-nitroso-aminomcthyl)cycloalkan-l-ol in the presence of Aliquat [47-49] and they have been shown to react in high yield with electron rich alkenes (see Section 7.3). Cyclopropylmethylidene, di(cyclopropyl)methylidene, and isopropylidene carbenes have been generated by an analogous route [49]. [Pg.310]
