Carbon disulfide reacts with the complexes (PEt3)3CuBPh4 (1) and (PPh3)3CuBPh4 (2), affording [(PEt3)2Cu(S2CPEt3)]BPh4 (3) and (PPh3)2Cu(S2CPh) (4), respectively. Compound 3 is formed by CS2 insertion into a copper-phosphorus bond; 4 is formed by copper-assisted phenylation of CS2 by BPh4-. The phosphoniodithiocarboxylate complexes 3 and [(PPh3)2Cu(S2CPEt3)]BPh4 (5) are obtained by addition of the zwitterion Et3P·CS2 to 1 and 2, respectively. The X-ray structure of 5 is reported. Pathways to the formation of 3 and 4 are proposed.
