Despite how the reaction is shown to proceed in Scheme 2, we suspect that a free carbocation is not likely to form and that the phenol serves to stabilize developing charge. This notion is supported by DFT studies with pincer ligated Pt-dicationic catalysts. See: Nowroozi-Isfahani, T.; Musaev, D. G.; Morokuma, K.; Gagné, M. R. Organometallics 2007, 26, 2540-2549.
