Lawesson's reagent (LR) has been shown to react with the N-heterocyclic carbenes [1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene (IMes) and 1,3-bis(2,6-diisopropylphenyl)imidazolidin-2-ylidene (SIPr)] to give adducts of the general form NHC·P(S)2-C6H4OCH3. Full characterizations, including X-ray crystal structures, are provided. The reaction of Woollins' reagent (WR) with IMes gave the known selanone, (IMes)Se.
Lawesson's 试剂（LR）已被证明可与 N-杂环卡宾[1,3-双（2,4,6-三甲基苯基）咪唑-2-亚基（IMes）和 1,3-双（2,6-二异丙基苯基）咪唑啉-2-亚基（SIPr）]反应，生成一般形式为 NHC·P(S)2-C6H4OCH3 的加合物。提供了完整的表征，包括 X 射线晶体结构。Woollins 试剂（WR）与 IMes 的反应得到了已知的硒酮，（IMes）Se。
