ABSTRACT:
There is provided a novel process for production of a 2-(substituted phenyl) -3,3,3-trifluoropropene.Disclosed is a process for production of a 2-(substituted phenyl)-3,3,3-trifluoropropene compound represented by the formula (7) or a salt thereof The process comprises reacting a compound represented by the formula (1) (X is an alkyl group, etc.) with a compound represented by the formula (2) (Y is a halogen atom, etc.) in the presence of a catalyst represented by the formula (3) (M is an ion of a metal belonging to Group 10 on the elementary periodic table which has an oxidation state number of 1 to 8; G is a unidentate or multidentate ligand; L is a phosphine compound represented by the formula (4) which is bound to the center metal M or is a carbene selected from those represented by the formulae (5) and (6), provided that L's may be same as or different from one another when a is 2 to 5; A represents a univalently or multivalently charged anion; b represents an integer of 1 to 3; a represents an integer of 1 to 5·b; c represents 0 or an integer of 1 to 4·b; and n represents an integer of 1 to 6).
