Arylboronic acids or potassium aryltrifluoroborates were readily oxidatively carbonylated to their corresponding diaryl ketones in high yields with high selectivities by ligand-freepalladium-catalyzedhomocoupling at atmospheric pressure. This novel method employs molecular oxygen or iodine as the oxidant and offers an attractive alternative to transition-metal-based oxidant systems.

on of unactivated benzyl chlorides with potassium aryltrifluoroborates usingCO gas has been developed. This reaction is transition-metal free, is carried out under ambient pressure, and provides a wide range of 1,2,3-triarylpropan-1-one derivatives in high yields. The novel method represents a significant improvement over the traditional palladium-catalyzed carbonylation.
四-N-丁基碘化铵 (TBAI) 使用 CO 气体催化未活化的苄基氯与芳基三氟硼酸钾的羰基化-苄基化反应已被开发出来。该反应不含过渡金属,在环境压力下进行,并以高产率提供范围广泛的 1,2,3-triarylpropan-1-one 衍生物。这种新方法是对传统钯催化羰基化的显着改进。
