REGIOSPECIFIC SILVER PROMOTED, PALLADIUM-CATALYZED INTRAMOLECULAR ADDITION OF ARYL IODIDES TO VINYL SULFONES

Jin, Zhendong,Fuchs, P. L.

, p. 5205 - 5208 (1993)

Treatment of aryl iodides with 5percent tetrakis(triphenylphosphine)palladium in the presence of silver nitrate and triethylamine in acetonitrile at reflux effects intramolecular conjugate-addition/reductive elimination to generate an annulated vinyl sulfone.Omission of the silver nitrate produces mixtures of vinyl and allyl sulfones.
