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-N^tBu) 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-N^tBu)GaCl] ₂ with a Ga-Ga single bond connecting the two units, as again shown by a single crystal X-ray diffraction analysis.
