應用
1,3-双(2,4,6-三甲基苯基)-1,3-二氢-2H-咪唑-2-亚烷基 (IMes) 是亲核的N-杂环卡宾 (NHC) 配体。
它可用于合成：
IMes还可用作芳基氯化物或芳基三氟甲磺酸盐与芳基硼酸的钯催化Suzuki-Miyaura交叉偶联反应中的辅助配体。
它可用于合成：
- IMes/铑络合物，其可用作将取代芳基和杂芳基硼酸酯选择性加氢生成顺式取代硼化环烷烃的催化剂。
- IMes/钌络合物 (Cp*Ru(IMes)Cl)(Cp* =η5-C5Me3)，其可用作烯烃关环复分解反应的催化剂。
IMes还可用作芳基氯化物或芳基三氟甲磺酸盐与芳基硼酸的钯催化Suzuki-Miyaura交叉偶联反应中的辅助配体。

In the search of smarter routes to control the conditions of N-heterocyclic carbene (NHCs) formation, a two-component air-stable NHC photogenerating system is reported. It relies on the irradiation at 365 nm of a mixture of 2-isopropylthioxanthone (ITX) with 1,3-bis(mesityl)imidazoli(ni)um tetraphenylborate. The
