AN UMPOLUNG OF ARYL AND VINYL HALIDES USING TRIS-(TRIMETHYLSILYL)ALUMINUM AND APROACH TO META- AND PARA-BRIDGED AROMATICS
Trost, Barry M.,Yoshida, Jun-ichi
, p. 4895 - 4898 (1983)
Nickel and palladium catalysts effect the chemoselective and stereocontrolled umpolung of aryl and vinyl halides to trimethylsilyl derivatives; this reaction permits a regioselective approach to cyclophanes.
