Method for synthesizing ether by catalyzing alcohol through trimethyl halosilane

The invention discloses a method for synthesizing ether by catalyzing alcohol through trimethyl halosilane. According to the method, under the conditions of air or nitrogen atmosphere, no solvent andno transition metal catalyst, an alcohol compound is directly used as a raw material, trimethyl halosilane is used as a catalyst, and symmetric or asymmetric ether is synthesized through one-step selective dehydration reaction. According to the method, the use of strong acid, strong base and organic primary halides with high toxicity, instability and higher price is avoided, the synthesis steps are shortened, the synthesis efficiency is improved, the reaction has good selectivity, and a target ether product can be obtained preferentially.

Development of dipyridine-based coordinative polymers for reusable heterogeneous catalysts

Poly(di(pyridin-2-yl)methyl acrylate) (PDPyMA), which was obtained by the free radical polymerization of designed coordinative monomer of di(pyridin-2-yl)methyl acrylate, is able to coordinate with various metal ions to form heterogeneous catalysts for diverse catalytic reactions. The Pd and Cu complexes supported by PDPyMA were developed for the heterogeneous Suzuki-Miyaura reaction and Friedel-Crafts alkylation, respectively. The PDPyMA-based catalysts showed no significant decline of reactivity after five times recycling. However, the hydrolysis of the PDPyMA backbone under alkaline conditions limited the catalytic efficiency of this heterogeneous catalyst so that the coordinative monomer was redesigned as 1,1-di(pyridine-2-yl)-2-(4-vinylphenyl)ethan-1-ol and then 2,2′-(1-methoxy-2-(4-vinylphenyl)ethane-1,1-diyl)dipyridine (MVPhDPy). With copolymerization of N-isopropyl acrylamide (NIPAM), the efficiency of polymer-based heterogeneous catalysts could be further raised, demonstrated by the increased turn over number in the Suzuki-Miyaura reaction, which approached 5,260 by using the catalyst formed from poly(MVPhDPy-co-NIPAM) and Pd(OAc)2. poly(MVPhDPy-co-NIPAM) copolymer, therefore, could be a versatile platform to support different metal ions for various heterogeneous catalytic reactions.
