Abstract

The first chiral tetracarbene indium(III) complexes have been synthesized by employing a rigid dianionic macrocyclic tetra-NHC ligand. The macrocyclic indium tetra-NHC bromide and ethoxide complexes are structurally similar to analagous salen complexes. The indium ethoxide complex effectively promotes living ring-opening polymerization of ε-caprolactone at room temperature.

ε-己内酯与大环四碳化铟络合物的开环聚合反应
采用刚性二阴离子大环四nhc配体合成了首个手性四羰基铟(III)配合物。大环四nhc溴化铟醚配合物在结构上与类似的salen配合物相似。氧化铟配合物能有效促进ε-己内酯室温开环聚合反应。
