Abstract: | Monomeric Dialkyl Metal Complexes of the R2M(NR′)2XR Type with M = Al, Ga, In, Tl; X = S, C and R, R′ = Alkyl and Silyl N,N′-Bis(trimethylsilyl)sulfurdiimide reacts with the trimethyl derivatives of aluminium, gallium, and indium within insertion. Hereby monomeric sulfinic acid imidamidates Me2M(NSiMe3)2SMe (Me = CH3) are formed. The lithium amidinates Li(NR′)2CMe (R′ = i-C3H7 and SiMe3) are formed likewise by insertion reactions with LiMe and the corresponding carbodiimides R′N?C?NR′ and were used in reactions with R2MCl (M = Al to Tl) to synthesize dialkyl metal amidinates R2M(NR′)2CMe. The NMR (1H and 13C) and the vibrational spectra (IR and Raman) are discussed and applied to describe the structure of these chelat complexes. |
