本文讨论了使用1，1-二膦酰胺配体合成Rh（I）和Ti（IV）金属中心的单-和杂环配合物。合成并分离了一个小的monophosphorus物种库：Ti用于与酰胺部分络合，而Rh用于与二膦结合。的顺序合成的杂环化合物物种开始从分离的Ti（酰胺化物）络合物，然后通过添加Rh前体在溶液中。通过NMR光谱法对配合物进行的质谱分析允许立体和空间识别这些具有挑战性的杂环化合物的合成和分离。
We herein discuss the use of 1,1-diphosphineamide ligands for the synthesis of mono- and heterobimetallic complexes of Rh(I) and Ti(IV) metal centers. A small library of monometallic species was synthesized and isolated: Ti was used to complex to the amide moiety, whereas Rh was used to bind to the diphosphine. The sequential synthesis of the heterobimetallic species started from isolation of the Ti(amidate) complex followed by addition of Rh precursors in solution. Meticulous analysis of the complexes by NMR spectroscopy allowed stereometric and spatial recognition of these challenging to synthesize and isolate heterobimetallic complexes.
