Abstract

Aminosilane bearing bulky substituents on nitrogen, LH₂(L = (NAr)₂SiPh₂, Ar = 2,6-ⁱPr₂C₆H₃) was reacted with n-BuLi (ratio 1:1) in toluene with a small amount of tetrahydrofuran resulting in [η¹-Ph₂Si(NHAr)ArNLi·2C₄H₈O] (1). Compound 1 was used to synthesize unusual monodentate complexes [(η¹-Ph₂SiNHAr)ArNSbCl₂] (2) and [(η¹-Ph₂SiNHAr)ArNSnMe₃] (3) by reacting with SbCl₃and Me₃SnCl, respectively. The three new compounds were characterized by elemental analysis,¹H NMR,¹³C NMR and single-crystal X-ray structural analysis. Compound 3 shows high catalytic activity in ring-opening polymerization (ROP) of ε-caprolactone (ε-CL).
