Unsymmetrical sulfides can be generated by the reaction of chlorine substituted aromatic compounds in sulfoxide in the presence of fluorine anion in fair yield.
Conducted in the ionic liquids, activated and inactivated halides, acyl chlorides, tosylate, and bezotriazolyl acylates were converted to corresponding azide an
A simple and efficient procedure for synthesis of 1-hydroxymcthylene-1,1-bisphosphoates from aldehydes is deseribed. This method was applied to the synthesis of
