hydroamination of amino-olefin substrates; the calcium complexes [Ca(NN(R))N(SiMe(3))(2)}(THF)] (R = (t)Bu, (i)Pr, Ph, 4-C(6)H(4)F) give enantioselectivities of up to 26% which marks a significant increase based upon literature precedence. The structure of [Ca(NN(Ph))N(SiMe(3))(2)}(py)] has been computed with density functional methods.
由手性1,2-二胺负载的钙络合物已被证明是用于氨基烯烃底物不对称加氢胺化的有效催化剂。钙络合物[Ca(NN(R))N(SiMe(3))(2)}(THF)](R =(t)Bu,(i)Pr,Ph,4-C(6)H( 4)F)给出高达26%的对映选择性,这表明基于文献的优先顺序大大提高了对映选择性。[Ca(NN(Ph))N(SiMe(3))(2)}(py)]的结构已通过密度泛函方法进行了计算。
