The chemistry of the novel TiII and TiIII amides, such as TiNMe22, TiNMe23 and Pi-C5H52TiNMe2 is described. Physical properties, including i.r., u.v., n.m.r., e.s.r., and mass spectra have been measured and interpreted structurally. The compounds are highly reactive and provide convenient sources for other d1 and d2 Ti complexes. The polymerisation of acrylonitrile initiated by titanium tetradimethylamide is described and discussed in some detail. A mechanism which adequately accounts for the behaviour is suggested and the kinetic consequences of the scheme are related to the experimental data. Related systems are described. Author
