Synthesis and Structure of a Titanium Hydrazido(2−) Complex
摘要:
Reaction of 1 equiv each of Ti(NMe2)(2)( dap)(2) ( 1), 1-hexyne, tert-butyl isocyanide, and 1,1-dimethylhydrazine at room temperature results in the formation of Ti(NNMe2)( dap)[ N(Bu-t) CHCHC(Bu-n) N(NMe2)-kappa N-2] ( 2), where one of the ligands is formed through iminohydrazination of the alkyne. A possible pathway for the generation of 2 and the crystal structure of this rare terminal hydrazido( 2-) complex of titanium are discussed.
