title: Novel ambiphilic dichlorocarbenoid equivalent in alkene cyclopropanation and carbonyl olefination.
abstract: The Ti-Mg-dichloromethylene complexes derived from the oxidative addition of CCl4 to the Mg-TiCl4 bimetallic species serve as a novel class of ambiphilic dichlorocarbenoid equivalents. Not only is Ti-Mg-dichlorocarbenoid highly selective but also it seems highly reactive in both alkene cyclopropanations and carbonyl dichloromethylenations.
