A novel 1,3,5-tris(alpha,beta,beta-trifluorovinyl)benzene monomer.

The reaction of the perfluoroalkenylzinc reagent, CF2=CFZnBr, with 1,3,5-tribromobenzene in the presence of a catalytic amount of Pd(Ph3)4 yielded a novel trifunctional monomer 1,3,5-tris(alpha,beta,beta-trifluorovinyl)benzene (1).
