An air stable copper(I)-phosphole complex, [CuCl2,5-bis(2-thienyl)-1-phenylphosphole}2] (1), was utilized as a catalyst in single and double A3-coupling reactions for preparing mono- and bi-propargylamines. A variety of aldehydes, amines and terminal alkynes were tested. Most of these reactions led to formation of the expected propargylamines in good yields using low amounts catalyst and obviating
空气稳定的铜(I)-磷配合物[CuCl 2,5-双(2-噻吩基)-1-苯基磷} 2 ](1)被用作单双A 3偶联反应的催化剂,用于制备单和双炔丙基胺。测试了各种醛,胺和末端炔烃。这些反应中的大多数导致使用少量催化剂以高收率形成预期的炔丙基胺,并且避免了使用手套箱那样的纯化试剂。
