The invention concerns a novel process for the manufacture of various aryloxyaliphatic aldehydes and related arylthio analogues, which are useful as chemical intermediates. The process involves reacting a dihalogenohydroxyalkane of the formula: HO.C(R.sup.2).sub.2.CHX.sub.2 wherein R.sup.2 is alkyl and X is chloro or bromo with a phenol or thiophenol in the presence of base and is applicable to large scale use.
这项发明涉及一种新的制造各种芳氧基脂肪醛和相关芳基硫醇类似物的过程,这些物质可用作化学中间体。该过程涉及在碱的存在下将公式为HO.C(R.sup.2).sub.2.CHX.sub.2的二卤代羟基烷与苯酚或硫代苯酚反应,其中R.sup.2为烷基,X为氯或溴,适用于大规模使用。
