NEW REACTION OF THIOCARBONYL YLIDES - INTERACTION OF S-ALKYL-N,N-DIMETHYLTHIOBENZIMIDIUM SALTS WITH ACTIVATED ACETYLENE DERIVATIVES LEADINGTO (E,E)-DIVINYL SULFIDES
Iv. Magedov et al., NEW REACTION OF THIOCARBONYL YLIDES - INTERACTION OF S-ALKYL-N,N-DIMETHYLTHIOBENZIMIDIUM SALTS WITH ACTIVATED ACETYLENE DERIVATIVES LEADINGTO (E,E)-DIVINYL SULFIDES, Russian chemical bulletin, 46(4), 1997, pp. 759-763
The reaction of thiocarbonyl ylides with activated acetylene derivativ
es gives (E,E)-divinyl sulfides in good yields. The reaction mechanism
is discussed and evidence in favor of the formation of a thiirane int
ermediate is presented.
