Base Treatment of Benzylic Selenonium Salts. Sigmatropic Rearrangements vs. Nucleophilic Displacement
Gassman, Paul G.,Miura, Takashi,Mossman, Allen
, p. 558 - 559 (1980)
Treatment of certain benzylic selenonium salts with a variety of bases resulted in nucleophilic attack to yield either an alkylation or a benzylation of the base, while the use of sodium amide in liquid ammonia as base generated a selenonium ylide which gave ortho substitution of the benzyl group via sigmatropic rearrangement.
