Abstract: A new type melamine-based porous organic polymers (SZU-1) has been synthesized with melamine and 2,2′-bipyridyl-5,5′-dialdehyde by a one-pot method and fully characterized. Divalent palladium salts were coordinated to this polymer network which successfully catalyzed the nucleophilic addition reaction of arylboronic acids to aromatic aldehydes. With only 1.0?mol% heterogeneous catalyst loading, high reaction yields (>?85%) can be achieved in most cases. The scope of substrates was also investigated and the catalyst showed universal applicability. Graphic Abstract: The loose and porous melamine-based porous organic polymers (SZU-1) are synthesized by melamine and 2,2′-bipyridyl-5,5′-dialdehyde. The performance of SZU-1 was characterized and most of the substrates achieved high yield (> 85%) in the catalytic performance test.[Figure not available: see fulltext.]

The technical solution and content of the invention relate to a synthesis method for a diaryl methanol compound shown as formula (I); the formula (I) is shown in the specification. The method includesthe following steps: under the existence of a palladium-sourced compound catalyst and organic phosphine ligand, in an organic solvent, an aldehyde derivative shown as formula (II) reacts with an organic cyclic triolborate compound shown as formula (III), and after the reaction is completed, post-processing is carried out, so that the diaryl methanol compound shown as formula (I) is obtained. According to the method, the reaction between the aldehyde compound and the organic cyclic triolborate compound can be smoothly carried out, so that the diaryl methanol compound can be obtained at high yield, a brand new synthesis route is provided for the synthesis of the compound, and a good application prospect and good industrial value are achieved.
