Metallo-Organic Compounds Containing Metal–nitrogen Bonds: Part Iv. Some Bis-(Primary Amino)-Titanium Compounds

The aminolysis reactions involving primary amines with either Ti(NMe2)4 or Ti(NEt2)4 have been studied. The primary amines behave as bifunctional reactants, forming colored, insoluble, non-volatile bis-(primary amino)-titanium compounds Ti(NR)2 which (except for R = C6H5) are highly reactive towards water or alcohols. With n-butylamine, some soluble polymers of the general formula Tix(NBun)2x−2(NEt2)4 were isolated. With tert-butyl-amine the dimers Ti2(NBut)2(NMe2)4 and Ti2(NBut)2(NHBut)2(NMe2)2 were obtained. The structures of these polymeric metal–nitrogen compounds are discussed.
