exists in equilibrium with its carbene form. Its reaction with thiophenes bearing at least one electron-accepting group was studied. Nucleophilic carbene insertion into Csp2−H bond of substituted thiophenes proceeded preferably at the 2(5) positions. Thiophenes featuring halogens at the 2 and 5 positions react much slower at the 3(4) position. A set of aldehyde was prepared. The reaction runs without
甲硅烷基甲脒与其卡宾形式平衡存在。研究了它与带有至少一个电子接受基团的噻吩的反应。亲核卡宾插入取代噻吩的 C sp2 -H 键中优选在 2(5) 位进行。在 2 和 5 位具有卤素的噻吩在 3(4) 位反应慢得多。制备了一组醛。反应在没有任何溶剂或催化剂的情况下进行。
