The chemistry of π-cyclopentadienyl nitrosyl molybdenum complexes. Part IV. Further studies of compounds containing bridging sulphur ligands

Abstract

Reaction of [(π-C₅H₅)Mo(NO)X₂]₂(X = Br or I) with RSH (R = Me, Et, Pr, Buⁱ, Bu, or CH₂Ph) gave [(π-C₅H₅)Mo(NO)(X)(SR)]₂ and reduction of this (X = Br) with zinc dust (X = Br) afforded [(π-C₅H₅)Mo(NO)SR]₂. The oxidation of the last with Cl₂ or Br₂ is briefly discussed. Treatment of [(π-C₅H₅)Mo(NO)X₂]₂ with NaSBuⁿ(X = Br) gave [(π-C₅)Mo(NO)(SPrⁿ)₂]₂ and with NaSPrⁱ(X = I) both [(π-C₅H₅)Mo(NO)(SPrⁱ)]₂ and [(π-C₅H₅)Mo(NO)(SPrⁱ)₂]₂. The mass, n.m.r., i.r., and electronic spectra of the compounds are described.
