Alcohol tertiary, ionic hydrogenation

Direct reductive elimination of the hydroxyl group can be achieved readily only for tertiary and benzylic alcohols, which are especially liable to form carbocationic intermediates in acidic media. These intermediates are able to abstract hydrogen from such hydride donors as triethylsilane. This procedure, ionic hydrogenation, was elaborated into a preparatively useful protocol ... [Pg.114]

Substitution. CsF is an excellent fluoride ion source for converting alkyl mesylates to RF, especially in the presence of the imidazolium mesylate 1. The effect, due to hydrogen bonding to the tertiary alcohol to render the fluoride ion more nucleophilic but less basic (so as to minimize elinination [H-OMs]), is also manifested in a polymer-linked 1, and a combination of r-AmOH and a polymer-supported ionic liquid. ... [Pg.99]
