Abstract

Described are the syntheses and structures of a phosphonium salt of the anionic ligand O-t-butyl-1,1-dithiooxalate, [PPh 3Bz][i-dto tBu] ([PPh 3Bz][1]), and of two Cu(I) complexes of this anion, Cu(PPh 3) 2(η 2-i-dto tBu) (2) and Cu(dmp)(PPh 3)(η 1-i-dto tBu) (3, dmp = 2,9-dimethyl-1,10-phenanthroline). In addition, it was found that the reaction of CuBr 2 with i-dto tBu - gives a O-t-butyl-1-perthio-1-thiooxalato complex of copper(I), [BzPh 3P][Cu(Br)(S-i-dto tBu)] ([BzPh 3P][4]), where [S-i-dto tBu] - is a disulfide-containing anionic ligand. The electronic structure and absorption spectrum of this species were investigated by time dependent DFT methods.
