This phenomenon can be used to help with catalyst recycling in Heck vinylation. See Bhanage, B.M.; et al. (1998). "Comparison of activity and selectivity of various metal-TPPTS complex catalysts in ethylene glycol — toluene biphasic Heck vinylation reactions of iodobenzene". Tetrahedron Letters. 39 (51): 9509–9512. doi:10.1016/S0040-4039(98)02225-4.
