Reaction of bulky organosilicon compounds with CS2: Cleavage and rearrangement reactions of 1,2-epoxides
摘要:
The reaction of tris(trimethylsilyl)methyllithium, (Me3Si)(3)CLi, and carbon disulfide with various epoxides have been studied. By an unusual rearrangement hydroxy-mercaptobis-(trimethylsilyl)-thiones have been synthesized in good yields. Unexpectedly, in the case of 2-phenyloxirane two structural isomers (2g) and (2h) have been formed which was confirmed by IR, H-1 and C-13 NMR spectroscopy. Moreover, the reaction of (PhMe2Si)(3)CLi and (Me3Si)(3)CLi with CS2 in the presence of epoxides has been compared. (C) 2014 Published by Elsevier B.V.
