Reaction of a large excess of H(2)S with 2 mol of (*)Cr(CO)(3)C(5)Me(5) yields HCr(CO)(3)C(5)Me(5) and HSCr(CO)(3)C(5)Me(5). Kinetic studies of this reaction show two reaction pathways are followed. At pressures of CO above 10-15 atm and temperatures 2HCr(CO)(3)C(5)Me(5) + C(5)Me(5)(CO)(2)Cr=S=Cr(CO)(2)C(5)Me(5) + 2CO occurs within minutes without formation of detectable amounts of HSCr(CO)(3)C(5)Me(5).
