Abstract
Two newethyltriphenylphosphoniumhalochromates,Et(Ph)3P[CrO3X], (X=Cl, Br):Mild and efficient reagents for oxidation of organic substrates
Author(s): Shahriare Ghammamy, Kheyrollah Mehrani, Saeid Maleki, Zahra JavanshirEthyltriphenylphosphonium chlorotrioxochromate, ETriPPCC and EthyltriphenylphosphoniumBromotrioxochromate, ETriPPBC, are newand efficient reagents that used for quantitative oxidation of several organic substrates. The facile oxidation of triphenylphosphine to triphenyl phosphine oxide by these reagents in CH3CN provides a clear cut indicating for oxygen atom transfer mechanism. These reagents are versatile reagents for the effective and nearly quantitative oxidation of organic substrates, in particular for alcohols, under mild conditions.
