In the same time, water-soluble bidental phosphines ligand BISBIS sulfonated 2,2''-bis(diphenylphosphinomethyl-1,1''-biphenyl was synthesized, and water-soluble rhodium complex Cl was synthesized in situ. This complex which was used as catalysts to catalyze the hydrogenation of avermectin was also tested. Although the rhodium complex containing bidentate phosphine BISBIS showed a higher catalytic activity than one containing TPPDS, the selectivity for ivermectin was lower. How to improve the selectivity will be needed to studied in futur.

Neoproterozoic Baoxing Complex in middle to lower metamorphic grade, located in western margin of Yangtze Craton, consists mainly of metamorphic gabbroic, dioritic gneisses, tonalitic and granodioritic gneisses, and massive monzogranites The studies of petrochemistry and SmNd isotopes of Baoxing Complex reveal that the gabbroic and dioritic magmas came from a congenetic magma derived from the partial melting of spinel lherzolites in depletive mantle, and that the magma was intensively contaminated by crustal materials during its emplacement The tonalitic and granodioritic magma were derived from the partial melting of metamorphic basalts in the lower crust And the monzogranitic magma was formed from partial melting of metagreywacks Integrating the lithological association, their trace elements, SmNd isotopic characteristics and petrogenesis, the Baoxing Complex must likely have been emplaced in an island arc tectonic background at the Neoproterozoic active continental margin of Yangtze Craton

位于扬子克拉通西缘的新元古代宝兴杂岩主要由中低级变质的辉长质片麻岩、闪长质片麻岩、英云闪长质到花岗闪长质片麻岩和块状二长花岗岩组成。岩石地球化学和SmNd同位素特征表明，辉长质片麻岩和闪长质片麻岩为同源岩浆演化序列，原始岩浆起源于亏损地幔尖晶石橄榄岩的部分熔融，在上升和侵位过程中受到了地壳岩石强烈混染。英云闪长质和花岗闪长质岩浆形成于下地壳玄武质岩石部分熔融，而二长花岗质岩浆形成于杂砂岩的部分熔融。综合分析宝兴杂岩的岩石组合、微量元素和同位素特征，该杂岩体最有可能形成于新元古代活动大陆边缘火山弧构造背景，并可能经历了碰撞过程。
