Activation of Cyanate Anions by Phosphine Radical Cations Enables Formal Hydrocarbamoylation of Alkenes. [PDF]
A photocatalytic formal hydrocarbamoylation reaction that employs a cyanate anion as the C1 source and provides N‐acyl iminophosphorane products from activated alkenes is described. Mechanistic investigations suggest generation of a phosphoranyl radical by addition of the cyanate anion to a phosphine radical cation, which enables the delivery of the ...

Novel Phosphonium-Based Ionic Liquid Electrolytes for Battery Applications
In this study, we address the fundamental question of the physicochemical and electrochemical properties of phosphonium-based ionic liquids containing the counter-ions bis(trifluoromethanesulfonyl)imide ([TFSI]−) and bis(fluorosulfonyl)imide ([FSI]−). To

Allenic Phosphonium Borate Zwitterions via a Transient Phosphonium Allenylidene [PDF]
We describe the synthesis of alkynyl phosphanes of the type R2P-C≡C-C(OCH3)Ph2, (R = Ph, Cy) and investigate their transformation to geminally substituted phosphonium borato-allene zwitterions upon their reaction with B(C6F5)3. The mechanism for this transformation was studied experimentally and by density functional theory computations (DFT ...
