Abstract
Additives that are good hydrogen-bond acceptors increase the efficiency of gold-catalyzed reactions in those instances where protodeauration is the rate-determining step. The efficiency of additives capable of hydrogen-bonding-assisted protodeauration correlated with their standing in a scale of hydrogen bonding basicity (measured by pKBHX). All additives used in the study are commercially available.
摘要
在质子消除为速率决定步骤的情况下，作为良好氢键受体的添加剂可以提高金催化反应的效率。能够通过氢键辅助质子消除的添加剂的效率与它们在氢键碱性尺度（通过 pKBHX 测量）上的位置相关。研究中使用的所有添加剂均为商业可得。
