摘要

NEW MATERIAL:A compound shown by formula I (R1 to R3 are hydrocarbon or dialkylamino; X- is anion capable of forming ion pair with phosphonium). EXAMPLE:(3,3,3-Trifluoro-2-hydroxypropyl)triphenylphosphonium=trifluor oacetate. USE:A raw material for drugs, agricultural chemicals, functional substances, etc. PREPARATION:3,3,3-Trifluoro-1,2-epoxypropane is reacted with a phosphine shown by formula II in the presence of an acid (preferably trifluoroacetic acid or trifluoromethanesulfonic acid) preferably at 0-50 deg.C.
