The invention discloses an alkynyl sulfone derivative, the structural general formula of which is as shown in formula (I), when R1 is methoxy, R2 is selected from 4-trifluoromethyl, 4-trifluoromethoxy, 4-tert-butyl, 4-bromine, 4-chlorine, 4-cyano and 2-methyl, and when R1 is methoxy, R2 is selected from 4-trifluoromethyl, 4-trifluoromethoxy, 4-tert-butyl, 4-bromine, 4-chlorine, 4-cyano and 2-methyl; when R1 is hydrogen, R2 is selected from 4-methyl and 4-phenyl; and when R2 is methyl, R1 is selected from thiophene, 4-chlorine, 4-isopropyl, 4-bromine and 4-ester group. The alkynyl sulfone compound is synthesized from benzenesulfonyl hydrazide and alkynyl bromide under the promotion of visible light, and the method is mild in reaction condition, free of harmful substances in the synthesis process, environmentally friendly, high in yield, low in cost, convenient to operate, capable of achieving small-dose reaction and suitable for industrial production. The alkynyl sulfone compound 1-14 provided ...
