Grignard reaction: alkylation with mercury halides

An alternative general approach to 4//-pyrans has been found recently in cathodic alkylation of 2,4,6-triphenylpyrylium perchlorate224 and might be useful, especially where the Grignard reaction (Eq. 9) fails. The salt is electrolyzed (mercury electrode) in the presence of a reactive alkyl halide two-electron reduction generates pyranyl anion 197, which is alkylated with RX to 4//-pyrans 165 (11 to 36%). [Pg.197]

Unsymmetrical diaryl-, dialkyl-, and alkyl(aryl)-mercury compounds are conveniently prepared by reaction of organomercuric halides with the necessary Grignard reagent 170... [Pg.774]
