NEW MATERIAL: Compounds expressed by formula I (R1-R5 are H, 1-6C alkyl which can be perfluorinated, halogen, 1-6C alkoxy, 1-6C alkylthione, three or less of R1-R5 are group excluding H, Y is H, CnF2n+1; X is Br, I; Alkyl is 1-3 alkyl).
EXAMPLE: (1-Phenyl-2,2,2-trifluoroethoxy)-tris(diethylamino)phosphonium bromide.
USE: Intermediates to be converted easily by one step into an organic compound having a partially fluorinated side chain which has been prepared so far only by a multi-step method requiring a huge expense.
PROCESS: A compound of formula I which is useful as the intermediate of a compound of formula IV (X can be H) is obtained easily in a good yield by one step from a raw material which can be produced easily by reacting a compound of formula II with both compounds of a formula CF3X (X is Br, I) and formula III.
