Abstract

The new complexes [M(CO)4(R2P(S)P(S)R2)], 1A-1D, 2A-2D, (1A, M = Mo, R = Me ; 1B, M = Mo, R = Et ; 1C, M = Mo, R = Pr-n ; 1D, M = Mo, R = Bu-n ; 2A, M = W, R = Me ; 2B ; M = W, R = Et ; 2C, M = W, R = Pr-n ; 2D, M = W, R = Bu-n) have been prepared either by the photochemical reaction of M(CO)6 with R2P(S)P(S)R2, or by thermal displacement of coordinated norbornadiene in C7H8Mo(CO)4 with R2P(S)P(S)R2, to give the complexes [M(CO)4(R2P(S)P(S)R2)]. The complexes have been characterized by elemental analysis, IR and 31P-[1H]-NMR spectroscopy and FAB-Mass spectrometry ; the spectroscopic studies suggest a cis-chelate bidentate coordination of the ligand.
