Metal-free Lewis acid mediated dehydrocoupling of phosphines and concurrent hydrogenation1. Issue 12 (11th February 2015) - Dobrovetsky, Roman
Abstract The stoichiometric reaction of trityl cation with two equivalents of Ph2PH affords the phosphine stabilized phosphenium salt [Ph2(H)PPPh2][B(C6F5)4] via hydride abstraction, while catalytic amounts of B(p-HC6F4)3 effects catalytic phosphine dehydrocoupling with the liberation of H2.
