Unusual ambiphilic carbenoid equivalent in amide cyclopropanation.
[reaction: see text] The titanium-methylene complexes derived from the TiCl(4)-Mg-CH(2)Cl(2) system serve as a novel class of ambiphilic carbenoid equivalents, which not only efficiently effect cyclopropanations of a variety amides but also exhibit high chemoselectivity.
