A novel and ligand-free method was developed for the decarboxylative cross-coupling of alkynylcarboxylic acids with arylboronic acids. By using an environmentally friendly H2O–poly(ethylene glycol) (PEG-400) system as the reaction medium, a series of internal alkynes were synthesized in good yields and with remarkable selectivity. The Pd(OAc)2–H2O–PEG-400 catalytic system could be used for up to three cycles without any loss of activity, demonstrating the robustness of the approach.

无配体且可回收的醋酸钯 (II) 在 PEG-400 水溶液中催化炔基羧酸与芳基硼酸的脱羧交叉偶联
开发了一种新的无配体方法，用于炔基羧酸与芳基硼酸的脱羧交叉偶联。通过使用环境友好的 H2O-聚（乙二醇）（PEG-400）体系作为反应介质，以良好的收率和显着的选择性合成了一系列内炔。Pd(OAc)2–H2O–PEG-400 催化系统最多可使用三个循环而不会损失任何活性，证明了该方法的稳健性。
