Abstract
The reaction of N,N-di((t)butyl)-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-((t)butylamino)-ethyl-((t)butyl)amide] Cl2Ga((BuNH)-Bu-t-CH2CH2-(NBu)-Bu-t) 1, the structure of which has been determined. Metallation of the same diamine with (t)butyl-lithium and GaCl3 (1:2:1) gave small quantities of the corresponding dinuclear, bicyclic gallium(II) compound 2, [((BuNH)-Bu-t-CH2CH2-(NBu)-Bu-t) GaCl](2) with a Ga-Ga single bond connecting the two units, as again Shown by a single crystal X-ray diffraction analysis.
