Double insertion of carbon disulfide into Pb-S bonds of lead(II) bis(arenethiolate): Synthesis and crystal structure of lead(II) bis(aryl trithiocarbonate)

摘要

The first lead(II) bis(aryl trithiocarbonate) compounds, (ArSCS2)(2)Pb (2a, Ar = Bbt (Bbt = 2,6-bis-[bis (trimethylsilyl)methyl]-4-[tris(trimethylsilyl)methyl]-phenyl); 2b, Ar = Tbt (Tbt = 2,4,6-tris[bis(trimethylsilyl)-methyl]phenyl)), were obtained by reaction of the corresponding Lead(ll) bis(arenethiolate) species, (ArS)2Pb: (1) with carbon disulfide. The crystal structure of 2a . CH2Cl2 was established by X-ray crystallographic analysis. The formation of 2 can be rationalized in terms of double insertion of carbon disulfide into two lead-sulfur bonds of 1. [References: 52]
