摘要
The oxidation of terminal alkenes was smoothly catalyzed by a recyclable and environmentally friendly catalytic system： [（C18H37）2N（CHa）213[PW4016]/H202/formic acid. This new catalytic system is not only capable of catalyzing oxidation of terminal alkenes with a phase-transfer character, but also under solvent-flee conditions, avoiding the use of chlorinated solvents. Many different kinds of terminal alkenes could be converted to the corresponding 1,2-diols of high purity in high yields. The catalyst could be easily separated and reused after reaction. Both flesh and used [（C18H37）2N（CH3）213[PW4016] catalyst was characterized bv Raman and FTIR.
