Abstract

The oxidative addition reaction of bis(4′,5′-di-methoxybenzo-)-1,2,5,6-tetrathiocin (1) to zero-valent Pt(PPh3)4 under microwave irradiation for 30 min afforded a mixture of the title Pt(II) complexes, (dmobdt)Pt(PPh3)2 (2) and [(dmobdt)Pt(PPh3)]2 (3) [dmobdt2− = 4,5-dimethoxybenzene-1,2-dithiolate]. Under extended reaction times the dimetallic complex 3 was isolated as the exclusive Pt-containing product indicating 2 is an intermediate en route to 3. The structures of 1–3 have been determined by X-ray diffraction.

Graphical abstractOxidative addition of bis-(dimethoxybenzo)-1,2,5,6-tetrathiocin to Pt(PPh3)4 affords (dmobdt)Pt(PPh3)2 which eliminates PPh3 to form the dimer Pt2(dmobdt)2(PPh3)2 [dmobdt2− = dimethoxybenzene dithiolate].Figure optionsDownload full-size imageDownload as PowerPoint slide
