ResumoThe 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 dibentate coordination of the ligand.
