Paragraph 0014; 0032-0034, (2018/04/01)
The invention relates to a method for synthesizing 2, 2 - [...] acid ethyl ester method, the glass in the reaction container, adding benzoin two thioether and 2, 6 - dimethyl - 1, 4 - dihydro - 3, 5 - pyridine dicarboxylic acid diethyl, replace the nitrogen glass after the air in the reaction container, adding butene and bromine two fluorine ethyl acetate, then adding solvent; the glass reaction container is placed on a blue light LED lamp or white light energy-saving lamp irradiation under 12 - 48 h, then remove the product in the solvent, adding petroleum ether product dissolved, adopts the 300 - 400 mesh silica gel as the stationary phase of column chromatography technology, wet in france type, in order to petroleum ether as eluent to elute, GC - MS detection product belt, and the collected [...] turns on lathe does, to get the. The method is simple in operation, solvent to the low quality requirement, can be corresponding to the multi-olefin, raw materials are easy, low cost, mild reaction conditions, and adopts a non-metal catalytic, preventing the metal residue.
