Abstract
Isocyanides react readily with UCp3R and U(C5Me5)2RCl (Cp cyclopentadienyl, R alky) to give iminoalkyl insertion compounds; with U(C5Me5)2R2, only one insertion reaction occurs, the second metal–carbon bond does not react; i.r. spectra of the insertion compounds exhibit unusually low CN stretching frequencies indicatives of strong metal–nitrogen bonding which causes non-equivalence in the Cp groups in the n.m.r. spectrum of UCp3{η2-CN(C6H3Me2-2,6)Bun}Keywords
