Abstract
Molecular nitrogen was incorporated into organic compounds via titanium nitrogen complex [TiNMg2Cl2·THF]. Namely, the reaction of titanium isocyanate complex [3THF· Mg2Cl2OTiNCO] prepared from titanium nitrogen complex [TiNMg2Cl2·THF] and CO2 with acid anhydrides afforded cyclic imides and quinazoline derivatives. Using the combination system of nitrogenation and palladium catalyzed carbonylation, phthalimide, isoindolinone, and quinazolines were synthesized from an aryl halide. Furthermore, coupling reaction of ketones with an aryl or vinyl halides in the presence of Pd (0) and titanium isocyanate complexes smoothly proceeded to give divinyl amines or arylvinyl amine via transmetalation.
