  4-叔丁基亚甲基环己烷加氢的立体化学

  摘要：

  在寻找选择性催化剂体系的过程中，已经研究了4-叔丁基亚甲基环己烷的催化加氢反应，该体系将大量产生顺式或反式-4-叔丁基甲基环己烷。可溶性和不溶性催化剂都已被采用。含丙-2-醇的溴化氢水溶液中的氯铂酸和氯化亚锡在室温和1个大气压下催化氢化，形成95％的顺式和5％的反式产物。相反，当将复杂的RhCl [（2-MeC 6 H 4）3 P] 2用于苯-乙醇溶液时，90％的顺式和10％的反式产品生产。在甲醇中用5％Rh–C氢化可产生88％的顺式和12％的反式异构体。

  Preparation of cyclic esters by hydrogenation of a carbonyl group in at least one anhydride radical —C(O)—O—C(O)— of a cyclic dicarboxylic or polycarboxylic anhydride by means of hydrogen in the presence of a homogeneous noble metal catalyst, characterized in that the hydrogenation is carried out in a homogeneous reaction mixture using an iridium catalyst. The cyclic esters are obtained in good chemical and optical yields when prochiral anhydrides are used together with chiral iridium catalysts.
