Enhanced Reactivity of N-heterocyclic Halophosphines and Phosphenium Cations: The Activation of Carbon―Heteroatom and Boron―Heteroatom Bonds
Original language description
N-heterocyclic phosphines (NHPs), and especially their ionic derivatives, phosphenium cations, have gained significant attention not only as isoelectronic species to N-heterocyclic carbenes (NHCs) but mainly, as highly Lewis acidic, active organocatalysts. A novel type of saturated NHPs has been introduced, with the nitrogen atoms substituted by phosphoramidothioates-{[kappa 2-O,O-(OCH2C(Me)2CH2O)P(= S)]2-mu-[NCH2CH2N]}PX, where X = F, Cl, Br, I, H, Ph, and their derivatives. Thanks to an increased positive charge at the P(III) atom, these compounds are prone to activate C & horbar.O, B & horbar.H, B & horbar.C, or B & horbar.F bonds and open cyclic ethers through the formation of intermediate species-phosphenium cations. The hydrido derivative can effectively catalyze the transfer hydrogenation of azobenzene by ammonia borane when irradiated by UV light at room temperature. The self-ionization of the iodido derivative promoted by the coordination of less sterically demanding N-heterocyclic carbene enables the isolation of a phosphenium cation.
