Phosphazenyl Phosphines: The Most Electron-Rich Uncharged Phosphorus Brønsted and Lewis Bases.
Angewandte Chemie, 2019It was discovered that phosphazenyl phosphines (PAPs) can be stronger P-superbases than the corresponding Schwesinger type phosphazene N-superbases. A simple synthetic access to this class of PR3 derivatives including their homologization is described ...

Catalyst-Free Arylation of Tertiary Phosphines with Diarylodonium Salts Enabled by Visible Light.
Chemistry, 2019The visible-light-induced arylation of tertiary phosphines with aryl(mesityl)iodonium triflates to produce the quaternary phosphonium salts occurs under mild, metal, and catalyst-free conditions.

Intramolecular Phosphine−Phosphine Donor−Acceptor Complexes
Inorganic Chemistry, 2009The reaction of 5-diphenoxyphosphanyl-6-diisopropylphosphinoacenaphthene 12 with chlorotrimethylsilane unexpectedly gave a phosphonium-phosphine compound 13, containing the structural motif of four phosphorus atoms connected in a chain. To explain the mechanism of this complex transformation, a proposed intermediate 5-dichlorophosphino-6 ...

Comprehensive Study of the Reactions Between Chelating Phosphines and Ni(cod)2
Organometallics, 2018A comprehensive study of the reactions of chelating phosphines with Ni(cod)2 to form (phosphine)Ni(cod), (phosphine)2Ni, or mixtures thereof is presented. A series of (phosphine)Ni(cod) complexes were isolated and characterized.

Bicyclic phosphines with two annulated, electronically unsaturated five-membered heterocycles are available through facile routes. In most cases, their phosphorus atoms are bound to heteroatoms such as oxygen or nitrogen (PN3 or PN2 O), whereas ...
