Question

急急急，求高人翻译！英译汉！

我知道这有点多，可是我实在是有太多单词找不到了，我学化学的本身英语底子就薄，很多在baidu上都找不出来，求求各位大虾帮帮忙！谢谢了！
Chelating phosphorus ligands with a rigid backbone and a large natural bite angle were applied in the nickel-catalysed hydrocyanation of styrene. The para substituents in the diphenylphosphanyl moiety of the 4,6-bis-(diphenylphosphanyl)-2,8-dimethylphenoxathiine (Thixantphos) ligands were varied and their electronic effects on the activity and selectivity of the catalytic experiments were investigated. The activity of the nickel complexes decreased when electron-donating substituents lead to a more basic phosphorus while electron-withdrawing substituents led to a higher activity. The results of variable temperature 31P-{1H} NMR experiments on the in situ catalysts are discussed in relationship to the catalytic performance. 4,6-Bis(diphenylphosphanyl)-2,8-dimethylphenoxathiine (Thixantphos) L1d and the complexes [NiCl2L1d ] 1 and [Ni(CN)2L1a] 2 (p-Me2N onphenyl) have been characterised by single-crystal X-ray diffraction. Complex 2 represents the first crystal structure of a monomeric dicyanonickel(II) complex with a P-P chelating ligand. The geometries of ligand L1d and complex1 were predicted by molecular mechanics calculations.

Answer 1

螯合磷配体的刚性骨干和一个大的自然咬角适用于镍催化hydrocyanation苯乙烯。该段在diphenylphosphanyl取代基的4,6 -二（ diphenylphosphanyl ） -2,8 - dimethylphenoxathiine （ Thixantphos ）配有各种电子影响的活性和选择性催化实验进行了调查。活动的镍配合物降低电子捐赠取代导致更基本的磷，而吸电子基取代导致了较高的活动。结果变温的31P - ） （氢核磁共振实验原位催化剂中讨论的关系，催化性能。 4,6 -双（ diphenylphosphanyl ） -2,8 - dimethylphenoxathiine （ Thixantphos ） L1d和物[ NiCl2L1d ] 1和[镍（架CN ） 2L1a ] 2 （个P - Me2N onphenyl ）已经特点是单晶X射线衍射。 2复杂的第一晶体结构的单体dicyanonickel （ II ）配合物的聚丙烯螯合配体。配体的几何形状的L1d和complex1预测的分子力学计算。

真的很难的，不是专家翻译不出来的。
