Description:
Four aluminum alkyl compounds, [CH{(CH 3 )CN-2,4,6-MeC 6 H 2 } 2 AlMe 2 ] ( 1 ), [CH{(CH 3 )CN-2,4,6-MeC 6 H 2 } 2 AlEt 2 ] ( 2 ), [CH{(CH 3 )CN-2- i PrC 6 H 4 } 2 AlMe 2 ] ( 3 ), and [CH{(CH 3 )CN-2- i PrC 6 H 4 } 2 AlEt 2 ] ( 4 ), bearing β -diketiminate ligands [CH{(Me)CN-2,4,6-MeC 6 H 2 }] 2 (L 1 H) and [CH{(Me)CN-2- i PrC 6 H 4 }] 2 (L 2 H) were obtained from the reactions of trimethylaluminum, triethylaluminum with the corresponding β -diketiminate, respectively. All compounds were characterized by 1 H NMR and 13 C NMR spectroscopy, single-crystal X-ray structural analysis, and elemental analysis. Compounds 1 – 4 were found to catalyze the ring-opening polymerization (ROP) of ε -caprolactone ( ε -CL) with good activity.
