摘要：

Methyltriphenylphosphonium Halochromates (MTriPPXC) were prepared and used for oxidation of alcohols under mild conditions. These new compounds are more efficient and have certain advantages over similar oxidizing agents in terms of the amount of oxidants, short reaction times, and high yields. Methyltriphenylphosphonium Halochromates, Me(Ph)(3)PCrO3X (MTriPPXC) (X= F, Cl, Br) are easily synthesized by the reaction of Methyltriphenylphosphonium with an aqueous solution of CrO3 and HX in a 1: 1: 2 mole ratio. The reactions were carried out in solution, under mild and acid-free conditions.
