Three New Tetraphenylphosphonium Halochromates (VI), [(C₆H₅)4P][CrO₃X], (X= F, Cl, Br): Efficient and Mild Reagents for Oxidation of Organic Substrates

Tetraphenylphosphonium Fluorochromate(VI), TPPFC, Tetraphenylphosphonium Chlorochromate(VI), TPPCC and Tetraphenylphosphonium Bromochromate(VI), TPPBC are new, mild and more efficient reagents which prepared easily and used for quantitative oxidation of several organic substrates. We have found that these reagents have certain advantages over similar oxidizing agents in terms of amounts of oxidants and solvents required, easier working up and high yields. These new compounds have certain advantages over similar oxidizing agents in terms of the amount of oxidants, short reaction times, and high yields.
