在无有机溶剂和无卤素的条件下，用30%的过氧化氢将芳香族和脂肪族硫化物氧化成亚砜或砜。二烷基和烷基芳基硫化物干净地氧化亚砜使用过氧化氢水溶液没有催化剂。合成砜的最佳催化剂为钨酸钠、苯基膦酸和甲基三辛基硫酸氢铵。在这种条件下，未存在的伯醇或仲醇或烯属部分不受影响。(C)2001爱思唯尔科技有限公司版权所有。
Aromatic and aliphatic sulfides are oxidized to sulfoxides or sulfones in high yield with 30% hydrogen peroxide under organic solvent- and halogen-free conditions. Dialkyl and alkyl aryl sulfides are cleanly oxidized to sulfoxides using aqueous hydrogen peroxide without catalysts. The best catalyst for the sulfone synthesis consists of sodium tungstate, phenylphosphonic acid, and methyltrioctyl-ammonium hydrogensulfate. Go-existing primary or secondary alcohol or olefinic moieties are unaffected under such conditions. (C) 2001 Elsevier Science Ltd. All rights reserved.
