ABSTRACT:
The invention concerns a method for functionalizing a double bond and, more particularly, a double bond bearing a metalloid atom. Said functionalization is produced by the action of perhalogenated sulphonyl chloride on the carbon bearing sulphur in the presence of a free radical initiator, preferably by homolytic cleavage. The invention is useful in organic synthesis.
