Nitrosylrhodium (14NO and15NO) Compounds Containing Triphenylphosphine

Electrochemistry of organophosphorus compounds. II. Electroreduction of triphenylphosphine and triphenylphosphine oxide

been investigated using polarography, cyclic voltammetry, coulometry, a n d product analysis. TPP proceeds by a one-electron transfer to form the anion radical which undergoes cleavage of a phenyl group. The electrochemical reduction of triphenylphosphine (TPP) and triphenylphosphine oxide (TPPO) has The reduction of everal recent papers have been concerned with the S polarography of triphenylp...

Triphenylphosphine oxide-catalyzed stereoselective poly- and dibromination of unsaturated compounds.

A novel PPh3O catalyzed bromophosphonium salt-mediated dibromination of α,β-unsaturated esters and β,γ-unsaturated α-ketoesters has been developed. The products were obtained with good to excellent yields and excellent diastereoselectivities. This dibromination reaction is a good complement to the field of dibromination.

Deoxygenative gem-difluoroolefination of carbonyl compounds with (chlorodifluoromethyl)trimethylsilane and triphenylphosphine

BACKGROUND 1,1-Difluoroalkenes cannot only be used as valuable precursors for organic synthesis, but also act as bioisosteres for enzyme inhibitors. Among various methods for their preparation, the carbonyl olefination with difluoromethylene phosphonium ylide represents one of the most straightforward methods. RESULTS The combination of (chlorodifluoromethyl)trimethylsilane (TMSCF2Cl) and tri...
