Patent

CA 2397834

The invention concerns a method for functionalising a double bond and, more particularly, a double bond bearing a metalloid atom. Said functionalisation 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.

La présente invention a pour objet un procédé de fonctionnalisation d'une double liaison et, plus particulièrement, d'une double liaison porteuse d'un atome de métalloïde. La fonctionnalisation est réalisée par l'action de chlorure de sulfonyle perhalogéné sur le carbone porteur du soufre en présence d'un initiateur de radicaux libres, de préférence par coupure homolytique. Application à la synthèse organique.
