A substituted paracyclophane is described of formula (I) wherein X1 and X2 are linking groups comprising between 2 to 4 carbon atoms, Y1 and Y2 are selected from the group consisting of hydrogen, halide, oxygen, nitrogen, alkyl, cycloalkyl, aryl or heteroaryl and Z is a substituted or unsubstituted alkyl group, aryl group or heteroaryl group. Preferably X1 and X2 are -(C2H4)- and Z is a substituted aryl group. The substituted paracyclophane provides transition metal catalysts that are useful in C-C and C-N bond formation and asymmetric hydrogenation reactions.
描述了一种代换的对环辛苯,其
化学式为(I),其中X1和X2是含有2到4个碳原子的连接基团,Y1和Y2从氢、卤素、氧、氮、烷基、环烷基、芳基或杂环芳基中选择,Z是一个取代或未取代的烷基基团、芳基或杂环芳基。最好X1和X2是-(
C2H4)-,Z是一个取代的芳基。这种代换的对环辛苯提供了在C-C和C-N键形成以及不对称氢化反应中有用的过渡
金属催化剂。
