Dithiocarbamato- and carbonyldithiocarbamato-complexes of rhenium-(I), -(III), -(IV), and -(V)
Abstract
Dithiocarbamato-complexes of rhenium such as Re(CO)(S2CNR2)3(R = Me, Et, PhCH2), ReCl2(S2CNR2)2(R = Et, PhCH2), and Re2O2S{S2CN(PhCH2)2}4, and complex ions such as [Re(S2CNEt2)4]+ and [Re(CO)3(S2CNEt2)X]–(X = Cl, I), have been prepared by interaction of Re(CO)5Cl and thiuram disulphides.
Interaction of Tl(S2CNEt2) and Re(CO)5Cl leads to [Re(CO)3(S2CNEt2)]2 which is easily cleaved by CO, pyridine, and PPh3 to Re(CO)3(S2CNEt2)(L).
The reaction of ReCl4(PPh3)2 with [Et2NCS2]2 leads to [Re2Cl2(Et2NCS2)5]Cl2 as well as ReCl2(S2CNEt2)2 and [Re(S2CNEt2)4]+.
