- W2040803631 abstract "The alkylideneamino-aluminium dihalides (R2C:NAlCl2)2(R = Ph or But) and (Ph2C:NAIBr2)n(n probably = 2) have been prepared from R2C:NLi and AIX3(X = Cl or Br); (Ph2C:NAICI2)2 has also been prepared from (diphenylmethyleneamino)trimethylsilane and aluminium trichloride. The trialkylideneamino-derivatives (R2C:N)3Al have been prepared from aluminium trichloride and R2C:NLi (3 molar equiv.). Attempts at the preparation of the dialkylideneamino-derivatives, (R2C:N)2AICI, from aluminium trichloride and R2C:NLi (2 molar equiv.) afforded mixtures of the mono- and tri-alkylideneamino-derivatives. The adduct py,AlCl3 was formed during the reaction between (Ph2C:NAICI2)2 and pyridine. Details of the i.r. and 1H n.m.r. spectra of these new moisture-sensitive methyleneamino-compounds are given and discussed, and the mass spectra of two compounds are reported. Four-membered (AIN)2 ring structures are proposed for the dimeric alkylideneaminoaluminium dihalides. For the monomeric trialkylideneamino-derivatives, the i.r. and 1H n.m.r. spectra are consistent with Iinear CN⇌Al units, the shape appropriate for maximum N⇌Al dative π-bonding from the methyleneamino-nitrogens to the three-co-ordinated aluminium." @default.
