The invention provides a use of cyclopropyl diphenylsulfonium trifluoromethanesulfonate as a sulfur ylide reagent and a method for preparation of four-membered cyclic ketone. The cyclopropyl diphenylsulfonium trifluoromethanesulfonate solves the problem that cyclopropyl diphenylsulfonium tetrafluoroborate as the traditional sulfur ylide reagent used in the synthesis of a four-membered cyclic ketone compound from aldehydes or ketones has large synthesis difficulty, complex operation and an expensive price. Under the same reaction conditions, the reactivity of cyclopropyl diphenylsulfonium trifluoromethanesulfonate is comparable to that of cyclopropyl diphenylsulfonium tetrafluoroborate and thus the cyclopropyl diphenylsulfonium trifluoromethanesulfonate can replace cyclopropyl diphenylsulfonium tetrafluoroborate and be used as a novel sulfur ylide reagent.
