SUBSTITUTION REACTIONS OF COMPLEXES (M=Mo, W; L-L=2,2'-BIPYRIDINE, 1,2-BIS(DIPHENYLPHOSPHINE)ETHANE) WITH XANTHATES AND DITHIOCARBAMATES

Article abstract of DOI:10.1016/S0022-328X(00)81029-3

The complexes (M = Mo, W, bipy = 2,2'-bipyridine) react with alkylxanthates (M^IRxant), and N-alkyldithiocarbamates (M^IRHdtc) (M^I = Na or K), yielding complexes of general formula (M = Mo, (S,S) = Rxant (R = Me, Et, t-Bu, Bz), Rhdtc (R = Me, Et); M = W, (S,S) = Extant).A monodentate coordination of the (S,S) ligand was deduced from spectral data.The reaction of with MeHdtc and Mexant gives the same complexes whether pyridine is present or not.The complexes ((S,S) = MeHdtc, Mexant) do not react with an excess of (S,S) ligand and pyridine.No reaction products were isolated from reaction of with xanthates or N-alkyldithiocarbamates.
