摘要:醇脱氢酶(adhs)被确定为还原相应的α,α-二卤代酮的合适酶,从而获得了具有出色转化率和对映体过量的光学纯的β,β-二氯或β,β-二溴代醇.在所测试的不同生物催化剂中,来自红球菌(rhodococcus Ruber)(adh-A),Ralstonia Sp.的adh .(rasadh),短乳杆菌(lbadh)和pr2Adh在活性和立体选择性方面被证明是最有效的.在进一步的研究中,研究了两种外消旋的α-取代的酮,即α-溴-α-氯和α-氯-α-氟苯乙酮,通过动态动力学过程获得了四种可能的非对映异构体之一.对于溴化衍生物,只有(1 R)-对映异构体是使用adh-A获得的,尽管存在适度的非对映异构体过量(> 99%ee,63%de),而氟化酮显示出较低的立体选择性(高达45%de).

摘要:The present invention relates to butadiene rubber polymers having low molecular weights and narrower molecular weight distributions than those known in the art. The present invention also relates to a metal-containing catalyst system, a solution polymerization process for the manufacture of said butadiene rubber, a one-pot process for the synthesis of the hydrogenated diene polymers, and a process for the hydrogenation of diene polymers.
