HgCl_2-Catalyzed monobenzylation and monoallylation reactions of 1-phenyl-l-alkynes

A general procedure for the HgCl2-mediated monolithiation reaction of 1-phenyl-l-alkynes was developed.

Mono-Allylation of Gem-Diacetates with Allylsamarium Bromide

The substitution reaction between gem-diacetates and allylsamarium bromide was investigated, and homoallylic alcohol acetates were obtained in moderate to good yields.
