A convenient palladium-catalyzed carbonylation reaction for the efficient synthesis of (E)-3-benzylidenechroman-4-ones has been developed. Using TFBen as a solid CO source, a range of substituted (E)-3-benzylidenechroman-4-ones were prepared in moderate to good yields with 2-iodophenols and allyl chlorides as the substrates. Additionally, substituted quinolin-4(1H)-ones can also be obtained with 2-iodoaniline as the starting material.
一种方便的钯催化羰基化反应已被开发用于高效合成(E)-3-亚苄基色满-4-酮。使用 TFBen 作为固体 CO 源，以 2-碘苯酚和烯丙基氯作为底物，可在中等至良好的产率下制备一系列取代的(E)-3-亚苄基色满-4-酮。此外，以 2-碘苯胺为起始原料，还可以得到取代的喹啉-4(1H)-酮。
