摘要:Functional long-chain alkyl disulfides were herein synthesized under liquid-liquid phase-transfer catalysis. The component of final products could be mainly controlled by feeding molar ratio of S/Na2S which factually dominated a chemical equilibrium among monosulfide, disulfide and trisulfide anions. The binding capability of sulfur anions with dimethyldidodecylammonium cation increases in the order of monosulfide < disulfide < trisulfide. Both the binding capability and the concentration of these sulfur anions determine which anion will be phase transferred and generate corresponding products in phase-transfer reaction. Such method can be used to directly synthesize functional long-chain alkyl disulfides of high purity. (C) 2016 Elsevier B.V. All rights reserved.
