Dichloroacetonitrile undergoes hydrogenation by triosmium dihydride cluster under mild conditions. The reaction of cluster complex (mu-H)(2)Os-3(CO)(10) (1) with CHCl2CN in the presence of morpholine as a base results in two novel compounds (mu-Cl)Os-3(CO)(10)(mu-N=CHCHCl2) (2) and (mu-H)Os-3(CO)(10)(mu,eta(2)-HN=CHCHCl2) (3). Both compounds were characterized using FTIR, C-13, H-1 NMR spectra, and CHN analysis, molecular structure of 2 was determined by X-Ray diffraction study. (C) 2017 Elsevier B.V. All rights reserved.
