Abstract

The optically active quaternary ammonium salt (S)-(−)-α-[(C6H5)CH(CH3)N(CH3)3I] reacts with AlR3 to afford optically active organoaluminum based inclusion compounds, liquid clathrates, of the formula (S)-(−)-α-[(C6H5)CH(CH3)N(CH3)3][Al2R6I] (R=CH3, C2H5). Specific rotation ([α] 25 D ) for the Al(CH3)3 compound was determined to be −13.19° while that for the Al(C2H5)3 analog was determined to be −14.30°. There are 13.8 toluene molecules per anionic moiety for the trimethylaluminum based liquid clathrate while there are 15.0 toluene molecules per anion for the corresponding triethylaluminum inclusion compound.
