deprotection steps have to be taken in the course of this type of preparation of the tripod ligands 3. By reaction with (CH3CN)3Mo(CO)3, ligands 3 form Mo(CO)4 derivatives 4 or Mo(CO)3 derivatives 5, depending on the reaction conditions. In compounds 4, the ligands are coordinated in a bidentate mode with the soft donor atoms (P, S) coordinated and the hard donor function playing the role of the dangling arm
基于新戊烷-三脚架配体CH的制备3 C(CH 2 X)(CH 2 Y)(CH 2 Z(3(X = NR 2,NHR; Y = PR 2 ; Z = PR 2,SR,S - )该程序基于伯胺或仲胺对官能化的氧杂环丁烷CH 3 C(CH 2 OCH 2)CH 2 R 1的氨解裂解,从而生成官能化的氨基醇CH 3 C(CH 2 NHR) (CH 2 OH)(CH 2 R)或CH 3C(CH 2 NR 2)-(CH 2 OH)(CH 2 R)2。2中存在的R(例如OR)和OH基团的适当激活可实现SR或PR 2供体功能的取代。根据在每个反应步骤中存在的基团的性质,在每个反应步骤中存在的各种保护基团和基团,在这种类型的三脚架配体3的制备过程中必须采取各种保护和脱保护步骤。通过与(CH 3 CN)3 Mo(CO)3反应,配体3形成Mo(CO)4衍生物4或Mo(CO)3衍生物5,取决于反应条件。在化合物4
