| titleOfInvention | The synthetic method of alkynyl sulfone |
| abstract | The present invention provides a kind of synthetic methods of alkynyl sulfone, comprising the following steps: by substrate The chloro- 1- methylpyridinium iodide of 2-, alkaline matter and organic solvent are mixed to form reaction system, react under room temperature, and substrate dehydration generates the alkynyl sulfone as shown in formula II；Wherein, R 1 For aryl, poly- aryl, alkyl, alkenyl, alkynyl, alkoxy and halohydrocarbyl；R 2 For aryl, poly- aryl, alkyl, alkenyl, alkynyl, alkoxy and halohydrocarbyl.The synthetic method of above-mentioned alkynyl sulfone has efficiently synthesized tri- key of C-C under conditions of not using transition metal, has avoided the metallic catalyst that overuses, reduce synthesis cost, improve the yield of synthesis, reduce the generation of by-product during synthesizing alkynyl sulfone.Further, alkynyl sulfone synthetic method of the invention uses " one kettle way ", and tri- key of one-step synthesis C-C reduces synthetic operation step, improves combined coefficient. |
