Abstract

Hexacarbonyltitanate(2-) reacts with azobenzene to provide 40-65% yields of [Ti(PhNNPh)(CO)4]2-, which is formulated as a 1,2-diphenylhydrazido dianion adduct of zerovalent titanium tetracarbonyl. The latter undergoes very facile hydrolysis to provide 1,2-diphenylhydrazine and the first hydroxo-carbonyl of titanium [Ti2(μ-OH)2(CO)8]2-, which has been structurally characterized as the [K(18-crown-6)]+ salt.
