Aryllithiums with increasing steric crowding and lipophilicity prepared from chlorides in diethyl ether. The first directly prepared room-temperature-stable dilithioarenes.


PMID 23113794

Abstract

A convenient procedure has been developed for the preparation of synthetically useful, room-temperature-stable aryllithiums starting from aryl chlorides and lithium metal. The method provides a route to aryllithiums which have previously not been accessible cleanly or could only be prepared by using more expensive starting materials.
