(PR 2 XR), and phosphites (P(XR) 3 ) have excellent catalytic properties for a variety of organic transformations. However, there has been surprisingly little research on the coordination chemistry of phosphonites. To help in remedying this deficiency, we have begun a study of the coordination chemistry of phosphonite ligands. In this project, seven new phosphonite ligands of the type RP(OR′O) (R = phenyl
摘要亚膦酸酯的过渡金属配合物作为催化剂是令人关注的,因为紧密相关的膦(PR 3),次膦酸酯(PR 2 XR)和亚磷酸酯(P(XR)3)的过渡金属配合物对多种有机物具有优异的催化性能。转变。然而,关于亚膦酸酯的配位化学的研究令人惊讶地很少。为了帮助弥补这种缺陷,我们已经开始对亚膦酸酯配体的配位化学进行研究。在这个项目中,有七个新的RP(OR'O)型亚膦酸酯配体(R =苯基,2-噻吩基; ORO = 1,1'-联-2-萘氧基,4-叔丁基苯氧基和儿茶酚氧基)及其已经合成了顺式-Mo(CO)4配合物。配合物的特征在于31 P,13 C和1 H NMR光谱,
