摘要

Reactions of [Pt2 (μ-S) 2 (PPh3) 4] with Ph3PbCl, Ph2PbI2, Ph2PbBr2 and Me3PbOAc result in the formation of bright yellow to orange solutions containing the cations [Pt2 (μ-S) 2 (PPh3) 4PbR3]+(R3= Ph3, Ph2I, Ph2Br, Me3) isolated as PF6− or BPh4− salts. In the case of the Me3Pb and Et3Pb systems, a prolonged reaction time results in formation of the alkylated species [Pt2 (μ-S)(μ-SR)(PPh3) 4]+(R= Me, Et). X-ray structure determinations ...
