Abstract
In the thermal decomposition of pentakis(diethylamido)tantalum, a novel organometallic compound, ethylimino(C,N)tris(diethylamido)tantalum (1), is isolated, which reacts with methyl isocyanate affording the insertion product (4). On heating (1) above 100°C, it decomposes to ethylimido-complex (2) and ethylene. The rate of the reaction is first-order with respect to the complex (1). The activation parameters at 144°C are calculated as ΔH\eweq=26.2 kcal/mole and ΔS\eweq=−8.3 e.u.Keywords
