Dichloroacetonitrile hydrogenation by osmium cluster: Crystal structure of (μ-Cl)Os 3 (CO) 10 (μ-N=CHCHCl 2 )

Abstract Dichloroacetonitrile undergoes hydrogenation by triosmium dihydride cluster under mild conditions. The reaction of cluster complex (μ-H) 2 Os 3 (CO) 10 ( 1 ) with CHCl 2 CN in the presence of morpholine as a base results in two novel compounds (μ-Cl)Os 3 (CO) 10 (μ-N=CHCHCl 2 ) ( 2 ) and (μ-H)Os 3 (CO) 10 (μ,η 2 -HN=CHCHCl 2 ) ( 3 ). Both compounds were characterized using FTIR, 13 C, 1 H NMR spectra, and CHN analysis, molecular structure of 2 was determined by X-Ray diffraction study.
