Synthesis of new hydrotris(pyrazolyl)-borate(Tp′) niobium terminal alkyne complexes and some reactions of these complexes was investigated. THF and diethyl ether were obtained after refluxing purple solutions of Na/benzophenone under dinitrogen. Deuterated nuclear magnetic resonance (NMR) solvents were dried over molecular sieves, degassed by freeze-pump-thaw cycles, and stored under dinitrogen. The thermoanalysis suggested that reversible migratory insertion yield hydride complexes, although the stability of these complexes has precluded a detailed investigation of the reaction course.
