Article abstract of DOI:10.1055/s-1987-27970

Benzyl alcohol is converted into a variety of α-substituted derivatives by a one-pot sequence involving lithiation of an intermediate hemicarbonate ester.Benzylamine is similarly converted by a one-pot sequence to α-substituted benzylamines: here an intermediate carbamate salt is involved.
