  drastically reduced reaction times affording biaryls in acceptable to good yields. With palladium(II) acetate as catalyst, electron-deficient aryl chlorides also reacted, affording a few biaryls in acceptable yields. Ullmann-type zinc-mediated homocoupling of iodo- and bromoaryls in the presence of Pd/C under CO2 atmosphere was achieved in aqueous media under US, though not under MW. Suzuki homo- and

  Pd催化的硼酸和芳基卤化物的均偶联和交叉偶联均在高强度超声（US）的水性介质中和在微波（MW）的DME中成功进行。采用Pd / C的多相催化，避免了膦配体和相转移催化剂。在一个涉及15种不同的碘代和溴代芳基以及7种硼酸的试验系列中，两种能源都大大减少了反应时间，从而使联芳基的收率令人满意。用乙酸钯（II）作为催化剂，缺电子的芳基氯化物也反应，以可接受的收率提供了一些联芳基。Pd / C存在下CO 2下Ullmann型锌介导的碘代和溴代芳基均偶联在美国条件下，在水性介质中达到了大气压力，但在兆瓦条件下却没有。Suzuki均质和交叉偶联也在我们实验室开发的新反应器中进行，该反应器采用了US和MW联合辐照技术，进一步改进了绿色合成方法。
