Treatment of the monomeric trialkylelement compounds Al(CMe3)3, Ga(CM e3)3, and In(CMe3)3 with different hydrazines H2N–N(H)R (R = Me, CMe3, C6H5) yielded the corresponding adducts (Me3C)3ENH2–N(H)R,1to9, in almost quantitative yields. All products were characterized by crystal structure determinations and shown to have the NH2group of the hydrazine ligands attached to the central Group 13 atom. These adducts are excellent starting compounds for the generation of hydrazides by thermolysis with release of butane.

Key words:Aluminum, Gallium, Indium, Hydrazines, Adducts
