Synthese und Kristallstruktur voniso-Butylimidogalliummethyl, [CH3Ga-NCH2CH(CH3)2]6
摘要:
The thermal decomposition of [Me2Ga-N(Bu-i)SnMe3](2) (prepared by the reaction of [(Me2SnNBu)-Bu-i](3) with GaMe3 in a 1:3 molar ratio) in an evacuated, sealed tube at 160 degrees C forms [(MeGaNBu)-Bu-i](6) in high yield and SnMe4. Mass, H-1 and C-13 NMR as well as some IR and Raman spectroscopic data are given and the crystal structure of this cage molecule with a hexagonal prismatic Ga6N6 skeleton has been determined.
Zur Reaktion voncyclo-Tristannazanen, [(CH3)2Sn-N(R)]3, mit den Trimethylderivaten des Aluminiums, Galliums und Indiums
摘要:
The cyclo-tristannazanes [Me2Sn-N(R)](3) (with R = Me, Pr-n,Pr-i,Bu-i) have been prepared from Me2SnCl2 and LiN(H)R in a 1:2 molar ratio. With MMe3 (M = Al, Ga, In) they form the dimeric dimethylmetal trimethylstannyl(alkyl)amides 1[Me2M-N(R)SnMe3](2) in good yields. The mass, NMR (H-1, C-13, Sn-119), and vibrational spectra are discussed and compared with the spectra of the tristannazanes. Thermolysis of the gallium amidocompounds splits SnMe4 to form methylgallium imido derivatives with cage structures. The crystal structures of selected stannylamido complexes have been determined by X-ray structure analysis.
