采用动力学和一种间接检测催化加氢反应中间体的新方法，研究了马来酸二甲酯在水溶液中使用阳离子铑配合物与水溶性双齿膦的加氢机理，从而检测到后期中间体。提出了一种机制，涉及快速，不可逆的底物结合，然后与氢的速率决定反应。(c)2006 Elsevier B.V.保留所有权利。
The mechanism for hydrogenation of dimethylmaleate in water using cationic rhodium complexes with water-soluble bi-dentate phosphines has been investigated using kinetics and a novel method for the indirect detection of intermediates in catalytic hydrogenation reactions, whereby a late intermediate was detected. A mechanism is proposed involving fast, irreversible substrate binding followed by a rate-determining reaction with dihydrogen. (c) 2006 Elsevier B.V. All rights reserved.
