Abstract

The reaction of the dialkylchloroborane BClR2 [R = CH(SiMe3)2] with aGroup 6 pentacarbonyl(cyano)metallate(0) [NEt4][M(CN)(CO)5] in CH2Cl2or PhMe gives the thermally stable complexes [M(CO)5(CNBR2)] [M = Cr (2a), Mo (2b), or W (2c)]. Crystalline 2a has a linear Cr-C-N-B skeleton with long Cr-C and B-N bonds and a short C-N bond, consistent (as are the IR, Raman and NMR spectra) with its formulation as [(OC)5CrBAR-C=N+-BR2].
