  名称：

  Adducts of organogallium chlorides with hydrazines and the formation of dimeric dialkylgallium hydrazides possessing different ring sizes

  摘要：

  The dialkylgallium chlorides R2GaCl (R = Me, Et, CMe3) reacted with hydrazines H2N-N(H)R' (R' = CMe3, C6H5) to form the adducts R2ClGa <- NH2-N(H)R' (1-4), in which the gallium atoms are coordinated by the NH2 nitrogen atoms of the hydrazine ligands. Treatment of these adducts with tert-butyllithium as a base afforded dialkylgallium hydrazides (R2Ga-N2H2R')(2) [5(R = R' = CMe3) and 6 (R = CMe3, R' = C6H5)] by deprotonation of the hydrazine ligands and precipitation of LiCl in two cases only. The remaining adducts gave a substitution reaction at gallium or an unclear reaction course. The hydrazides 5 and 6 adopt different structures in the solid state. The tri(tert-butyl) compound 5 possesses a four-membered Ga2N2 heterocycle in its molecular core with two exocyclic N-N bonds, which represents the structural motif usually observed for dialkylgallium hydrazides. 6 has a five-membered Ga2N3 heterocycle with one endocyclic and one exocyclic N-N bond. That structure is preserved in solution as clearly shown by NMR spectroscopy. The behaviour of 5 in solution is more complicated, which may be caused by cis/trans isomerization.
