Abstract
Difluoro(phenylsulfanyl)methane (PhSCF2H) was found to undergo a reaction with aromatic compounds mediated by SnCl4, through a thionium intermediate characterized by NMR and TD-DFT analyses, leading to the formation of a mixture of S,S′-diphenyl dithioacetal and aromatic aldehyde which, after oxidative hydrolysis, provides the aromatic aldehyde in good to excellent yields. The salient feature of the present work is the reaction of activated aromatic compounds containing a deactivating ester functional group, leading to the formylated products in good yields.

摘要
二氟（苯基硫基）甲烷（PhSCF 2 2H），发现发生反应与由的SnCl介导的芳族化合物4，通过一个thionium中间体，其特征在于用NMR和TD-DFT分析，导致的混合物的形成小号，小号' -二苯基二硫缩醛和芳族醛，在氧化水解后，以良好或优异的收率提供芳族醛。本发明的显着特征是含有失活酯官能团的活化芳族化合物的反应，从而以高收率得到甲酰化产物。
