| titleOfInvention | A kind of method for preparing substitution ethyl aryl sulfone |
| abstract | The invention discloses a kind of method for preparing substitution ethyl aryl sulfone.This method is：Compound and alkali shown in compound shown in Formula II, formula III are mixed coupling reaction is carried out in solvent, reaction, which is finished, obtains R 2 ' it is CH 2 CH 2 R 2 The Formulas I shown in compound；Or comprise the following steps：Compound shown in Formula II, ethyl propiolate and alkali are mixed coupling reaction is carried out in solvent, reaction, which is finished, obtains R 2 ' it is CH=CHC=OOCH 2 CH 3 The Formulas I shown in compound.This method, pervasive, convenient, reaction system is simple, and reaction condition is gentle, and is very easy to be amplified to a gram level, reaction raw materials it is simple and easy to get, used alkali and raw material are also very cheap and easy to get, and atom utilization is higher, and solvent toxicity is low. |
