(aminopyrimidinato)titanium complex has been synthesised from inexpensive and easily accessible 2-(tert-butylamino)pyrimidine and [Ti(NMe2)4] and used as a catalyst for the intermolecular hydroamination of alkynes as well as the cyclization of aminoalkenes. The hydroamination reactions of 1-phenylpropyne and terminal arylalkynes deliver the corresponding anti-Markovnikov addition products with excellent yields and
一种新的(氨基嘧啶合)钛络合物已由廉价且易于获得的 2-(叔丁基氨基)嘧啶和 [Ti(NMe2)4] 合成,并用作炔烃分子间加氢胺化以及氨基烯烃环化的催化剂。1-苯基丙炔和末端芳基炔烃的加氢胺化反应以优异的产率和区域选择性提供相应的反马尔科夫尼科夫加成产物。
