Together with a strongly oxidizing polyoxometalate, H5PV2Mo10O40, PtII(N-(2,6-diisopropylphenyl)pyrazin-2-ylmethanimine)Cl2 forms a combined catalyst that was active in the tandem pinacol coupling-rearrangement of aryl aldehydes to give mostly the corresponding diarylacetaldehyde in high yields using molecular hydrogen as the reducing agent.
一种强氧化性的多金属氧酸盐H5PV2Mo10O40与PtII(N-(2,6-二异丙基苯基)吡嗪-2-亚甲亚胺)Cl2组成的复合催化剂,在以分子氢为还原剂的条件下,对芳基醛的联苯偶联-重排反应展现出活性,能够高产率地得到相应的二芳基乙二醛。
