The reaction of Mes2CC(OH)SiMe2R (RMe, SiMe3) with SOCl2 gives the rearrangedelimination product MesCCMes, presumably via β-mesityl participation in the solvolysis of the derived OSOCl derivative, followed by “Me3Si+“ loss from the rearranged ion MesC(Me3Si)C-Mes. Under the same conditions, the carbon analogue Mes2CC(OH)Bu-t gives the ketone Mes2CHCOBu-t and benzofurans via non-solvolytic reactions
ME的反应2 CC(OH)森达2 R(RMe,森达3)用的SOCl 2给出了重排的消除产物MesCCMes,通过在派生OSOCl衍生物的溶剂解β-基参与推测,随后重排离子MesC(Me 3 Si)C-Mes引起的“ Me 3 Si + ”损失。在相同条件下,碳类似物的Mes 2 CC(OH)卜叔给出了酮的Mes 2经由非溶剂化反应CHCOBu-t和苯并呋喃。
