The synthesis and characterization of a series of primary and secondary alcohol adducts of 1,3-dimesitylimidazolin-2-ylidene is described. These adducts are stable as solids at room temperature, but readily release alcohol and the free carbene in solution. These alcohol adducts function as excellent single-component catalyst/initiators for the ring-opening polymerization of lactide under mild conditions, providing polymers with controlled molecular weights and narrow polydispersities. Multifunctional adducts were used to prepare poly(lactide)s of more complex architectures.
描述了一系列1,3-二甲基咪唑啉-2-亚基的伯醇和仲醇加合物的合成与表征。这些加合物在室温下作为固体是稳定的，但在溶液中容易释放出醇和游离卡宾。这些醇加合物在温和条件下作为丙交酯开环聚合的优异单组分催化剂/引发剂，可提供具有可控分子量和窄多分散性的聚合物。多功能加合物用于制备结构更复杂的聚丙交酯。
