环（烷基）（氨基）苯（CAAC）与二氯和二溴双（三甲基硅基）氨基硼烷反应生成卤代氨基硼烷-CAAC加合物。当使用碘类似物时，在碳中心的氧化加成得到一个阳离子亚氨基溴- caac加合物，具有硼氮三键。从氯和溴亚氨基溴- caac加合物中提取卤化物也可得到类似的盐。讨论了所有这些化合物对CO2的反应性。
The reaction of a cyclic (alkyl)(amino) carbene (CAAC) with dichloro-and dibromobis(trimethylsilyl) aminoborane results in the formation of haloiminoborane-CAAC adducts. When the iodo analogue is used, an oxidative addition at the carbene center affords a cationic iminoboryl-CAAC adduct, featuring a boron-nitrogen triple bond. Similar salts are also obtained by halide abstraction from the chloro-and bromoiminoborane-CAAC adducts. The reactivity of all of these compounds towards CO2 is discussed.
