Abstract

The reaction of N,N′-di(tbutyl)-ethane-1,2-diamine with NaH followed by anhydrous GaCl3 (molar ratios 1:2:1) gives mainly an insoluble bis(diamido)gallium chloride together with a low yield (28%) of a soluble monocyclic dichlorogallium-[2-(tbutylamino)-ethyl-(tbutyl)amide], Cl2Ga(tBuNH-CH2CH2-NtBu) 1, the structure of which has been determined. Metallation of the same diamine with tbutyl-lithium and GaCl3 (1:2:1) gave small quantities of the corresponding dinuclear, bicyclic gallium(II) compound 2, [(tBuNH-CH2CH2-NtBu)GaCl] 2 with a Ga-Ga single bond connecting the two units, as again shown by a single crystal X-ray diffraction analysis.
