Ti-Pd alloy catalysts were developed for the cross β-arylmethylation between arylmethylalcohols and different primary alcohols via a hydrogen autotransfer mechanism. The alloy catalysts could be reused multiple times without the need for pre-activation. Analysis of the reaction solution by inductively coupled plasma atomic absorption spectroscopy indicated that only a minimal amount of Ti and no Pd was leached from the catalyst.
通过氢自转移机制开发了用于芳基甲醇与不同伯醇之间交叉β-芳基甲基化反应的钛钯合金催化剂。该合金催化剂无需预活化即可多次重复使用。通过电感耦合等离子体原子吸收光谱法对反应溶液进行分析表明，催化剂中只有极少量的钛被浸出，且没有钯被浸出。
