  The study on application of palladium(II) acetate as catalyst in transvinylation reactions of hydroxycinnamic acids has been done. This study was intended to assess the capability of palladium(II) acetate as a safer replacement for mercuric(II) catalysts in transvinylation reactions of hydroxycinnamic acids and its derivatives. Optimizing the performance of the catalyst by applying several additional catalysts in the reactions was firstly done. Among those catalysts, KOH and H2SO4 showed significant impacts on the yields of the transvinylation reactions. It increased to 96 % when KOH was added and to 95 % when H2SO4 was added, compared to only 66 % when palladium(II) acetate alone was employed. Adding either KOH or H2SO4 along with the primary catalyst of palladium(II) acetate in transvinylation reactions of hydroxycinnamic acids gave the desired products in good yields. This proved that palladium(II) acetate was capable of catalyzing the transvinylation reactions of hydroxycinnamic acid and its derivatives to produce some vinyl esters.

  已经完成了关于醋酸钯（II）在羟基肉桂酸的转乙烯基化反应中作为催化剂的应用研究。这项研究旨在评估醋酸钯（II）作为汞（II）催化剂的更安全替代品在羟基肉桂酸及其衍生物的转乙烯基化反应中的能力。首先通过在反应中添加几种额外的催化剂来优化催化剂的性能。在这些催化剂中，KOH和H2SO4对转乙烯基化反应的产量有显著影响。与单独使用醋酸钯（II）时只有66%的产量相比，添加KOH时产量增加到96%，添加H2SO4时增加到95%。在羟基肉桂酸的转乙烯基化反应中，添加KOH或H2SO4以及主要催化剂醋酸钯（II）都能获得高产量的理想产物。这证明醋酸钯（II）能够催化羟基肉桂酸及其衍生物的转乙烯基化反应，生成一些乙烯酯。
