A series of new stereoretentive ruthenium catalysts bearing the dithiocatecholate ligand was synthesiszed on the basis of the M7 and Ru–benzylidene–oxazinone design. The activity of the catalysts was tested in ring-opening cross-metathesis reactions, ring-closing metathesis reactions, cross-metathesis reactions, and self-metathesis reactions using Z- and E-configured starting materials. The desired metathesis products were obtained with moderate to high yields and with excellent stereoselectivities (>95%). Substrate-dependent reactivity was found by carrying out kinetic studies on internal and terminal olefins.

基于M7和Ru-苄叉基-恶嗪酮设计的立体定向钌催化剂的合成与应用

在M7和Ru-亚苄基-恶嗪酮设计的基础上，合成了一系列带有二硫代邻苯二酚配体的新型立体保持性钌催化剂。使用Z-和E-构型的起始原料，在开环交叉复分解反应，闭环复分解反应，交叉复分解反应和自复分解反应中测试了催化剂的活性。获得所需的复分解产物，具有中等至高产率，并具有优异的立体选择性（> 95％）。通过对内烯烃和末端烯烃进行动力学研究，发现了与底物有关的反应性。
