  Syntheses and Theoretical and Mechanistic Aspects of 1-Thia-2,4- and 1-Thia-3,4-diphosphole Formed from CS₂ and ^tBuCP and Crystal and Molecular Structure of the First 1-Thia-3,4-diphosphole Complex:  cis-[{PtCl₂(PEt₃)}₂(P₂SC₂^tBu₂)]

  摘要：

  The reaction of (BuCP)-Bu-1 with CS2 (or its ylide type complexes such as R3PCS2 (R = Et, Ph, cyclohexyl), (C5H10N)(2)CCS2, or (C4H8NO)(2)CCS2) gives a mixture of 3,5-di-tert-butyl-1-thia-2,4-diphosphole and 2,5-di-tert-butyl-1-thia-3,4-diphosphole, which were characterized by NMR spectroscopy. The latter was also characterized by the single-crystal X-ray structure determination of its bis(platinum(II)) complex [(PtCl2PEt3)(2)(mu-(P2SC2Bu2)-Bu-t)] This is the first structural characterization of a 1-thia-3,4-diphosphole ring. The mechanism of these reactions was explored by B3LTP/6-311+G** level quantum chemical calculations. The reaction pathway involves a phosphadithiolediylcarbene and its diphosphatetrathiafulvalene dimer as intermediates. Several other possible reaction pathways were ruled out.
