CATALYSTS FOR ARYL SULFIDE SYNTHESIS AND METHOD OF PRODUCING ARYL SULFIDES

摘要

The present invention relates to the formation of aryl sulfides and aryl thiols from aryl halides and thiols, thiolates or thiolate equivalents. The present invention provides a catalyst for the coupling of aryl halides with alkyl or aryl thiols or a hydrogen sulfide equivalent to form aryl alkyl, aryl silyl or diaryl sulfides. The reaction encompasses bromoarenes and other similar compounds containing leaving groups as well as nitrile, ester, keto, free hydroxyl, free amino, free carboxylic acid and other common functionalities. The invention can be used to prepare pharmaceutical compounds, especially including their intermediates, agricultural agents and aryl sulfide polymers.
