A joint experimental/computational effort to elucidate the mechanism of dihydrogen activation by a gold(I)/platinum(0) metal-only frustrated Lewis pair (FLP) is described herein. The drastic effects on H2 activation derived from subtle ligand modifications have also been investigated. The importance of the balance between bimetallic adduct formation and complete frustration has been interrogated, providing for the first time evidence for genuine metal-only FLP reactivity in solution. The origin of a strong inverse kinetic isotopic effect has also been clarified, offering further support for the proposed bimetallic FLP-type cleavage of dihydrogen.

用Gold（I）/ Platinum（0）系统对双氢进行真正的双金属阻抑路易斯对活化的证据。

本文描述了联合实验/计算努力，以阐明仅由金（I）/铂（0）金属失意的路易斯对（FLP）激活二氢的机理。还研究了源自微妙的配体修饰对H2活化的剧烈影响。人们一直在质疑双金属加合物形成与完全失意之间平衡的重要性，这首次为溶液中纯金属的纯FLP反应性提供了证据。还已经阐明了强烈的逆动力学同位素效应的起源，为拟议的双金属双金属FLP型裂解提供了进一步的支持。
