Abstract

The reactions of InCl3 with two and three equivalents of lithium (2-dimethylaminomethyl)pyrrolate (1) in diethyl ether solutions afford In[C4H3N(CH2NMe2)]2Cl (2) and In[C4H3N(CH2NMe2)]3 (3) in 92% and 50% yield, respectively. Subsequent reactions of 2 with MeLi and Li(CCPh) yield In[C4H3N(CH2NMe 2)]2Me (4) and In[C4H3N(CH 2NMe2)]2(CCPh) (5), respectively. All compounds were confirmed by 1H and 13C NMR spectroscopy and compounds 3, 4, and 5 were further characterized by single-crystal X-ray crystallography. Compounds 2, 3, and 4 showed moderate catalytic activity toward the ring-opening polymerization of ε-caprolactone.
