  A highly efficient heterogeneous palladium-catalyzed carbonylative cyclization of aryl iodides and 2-hydroxyacetophenones is developed. The reaction proceeds efficiently in DMSO at 120 °C under 3 bar of carbon monoxide by using 2 mol% of an MCM-41-immobilized bidentate phosphine palladium complex [MCM-41-2P-Pd(OAc)2] as the catalyst and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as the base, providing

  开发了一种高效的多相钯催化的芳基碘化物和 2-羟基苯乙酮的羰基环化反应。通过使用 2 mol% 的 MCM-41 固定的二齿膦钯配合物 [MCM-41-2P-Pd(OAc) 2 ] 作为催化剂和 1 ,8-二氮杂双环[5.4.0]undec-7-ene (DBU) 为基础，提供了一种通用、高效和实用的方法，用于从容易获得的起始材料中以高产率组装多种黄酮类化合物。这种负载的钯催化剂可以很容易地通过反应混合物的离心来回收，并且可以循环使用超过 9 次，而不会显着降低其催化效率。

  An efficient cross-coupling of 3-iodochromones with triarylbismuths under catalytic palladium conditions is reported. Triarylbismuths were employed as substoichiometric multicoupling nucleophiles for the synthesis of a variety of substituted isoflavones. Under the established protocol, cross-coupling reactions were found to be very efficient, furnishing high yields of products.
