Abstract

Straightforward, multigram synthesis of the new diamide–diamine proligand H₂N₂NN′ [N₂NN′ = (2-NC₅H₄)CH₂N(CH₂CH₂ NSiMe₃)₂] is described along with a preliminary survey of the five- and six-coordinate, neutral and cationic, single- and multiply-bonded complexes of groups 3, 4 and 5 that it can support; the related bis(alkoxide)–diamine proligand H₂O₂NN′ is also described where H₂O₂NN′ = (2-NC₅H₄)CH₂N(CH₂CMe₂ OH)₂.
