SPONTANEOUS -SIGMATROPIC REARRANGEMENT OF S-ARYLTHIOSULFONIUM YLIDS FORMED IN THE REACTION OF ARYLSULFENYL CHLORIDES WITH METHYLTHIOMETHYLTRIMETHYLSILANE
Gassman, Paul G.,Miura, Takashi
, p. 4787 - 4790 (1981)
A new -sigmatropic rearrangement of thiosulfonium ylids yields ortho-methylthiomethylthiophenols.The ylids were generated through the cleavage of a C-Si bond with chloride anion.
