Dr. Aris et al., METALLACYCLES OF THE IMIDOYLAMIDINATO COMPOUNDS HNC(R)NC(R)NH AND GROUP-13 ELEMENTS - CRYSTAL-STRUCTURE OF THE COMPLEX [GAME(2)(HNC(CF3)NC(CF3)NH)], Journal of the Chemical Society. Dalton transactions, (6), 1997, pp. 909-910
Reaction of trimethylgallium with trifluoroacetamidine [H2NC(CF3)NH] r
esulted in an unusual elimination reaction, and yielded the air-stable
volatile metallacycle [GaMe(2){HNC(CF3)NC(CF3)NH}] which shows a plan
ar six-membered (GaNCNCN) ring; a related aluminium system. [AlMe(2){H
NC(Ph)NC(Ph)NH}] was formed using benzamidine [H2NC(Ph)NH].
