Stable vinylating agent. Darses et al, reported the cross-coupling reaction with arenediazonium tetrafluoroborates to give styrenes in high yield, catalyzed by Pd(OAc)2 (ligand-free) or the palladacycle trans-Di-μ-acetatobis[2-(di-o-tolyl-phosphino)-benzyl-]dipalladium(II)-: Tetrahedron Lett., 39, 5045 (1998); Eur. J. Org. Chem., 1875 (1999). Molander has since described the direct cross-coupling of the reagent with aryl halides and triflates, catalyzed by [1,1'-Bis(diphenyl-phosphino)-ferrocene]palladium(II)- chloride: Org. Lett., 4, 107 (2002).
