Carbon Dioxide. A Reagent for the Protection of Nucleophilic Centers and the Simultaneous Activation for Electrophilic Attack. Part 4. The α-Substitution of (i) Benzyl Alcohol and (ii) Benzylamine

, p. 415 - 418 (1987)
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.
Insertion of isocyanates, CO2, and ethylene carbonate into the Zr-C and Zr-N bonds of imine complexes. Construction of chiral centers like those in α-amino acids
Gately, Daniel A.,Norton, Jack R.,Goodson, Patricia A.
, p. 986 - 995 (2007/10/02)
In some cases zirconocene-imine complexes insert CO2; more generally they insert isocyanates and cyclic carbonates. Isocyanates can insert into either the Zr-C or the Zr-N bond; protonolysis of the zirconacycle resulting from Zr-C insertion giv
