Herein, we report a novel protocol for the photochemical generation of thioaldehydes in a continuous flow process which were in situ reacted with electron rich 1,3-butadienes in thia-Diels–Alder reactions. A broad range of 3,6-dihydro-2H-thiopyrans were formed as products in much higher yields and productivities as compared to classical batch processes. Moreover, greatly reduced reaction times and a facile large-scale preparation of products were achieved by fully exploiting the advantages of continuous flow technology.

Thioaldehydes containing virtually any α-substitutent can be generated by photofragmentation of phenacyl sulfides.Donor-substituted derivatives are reactive toward electron-rich dienes and give 2 + 4 cycloadducts with regiochemistry corresponding to advan

Acyclic thioiminium salts and the condensed thiazolium salts in the presence of aqueous sodium hydroxide as such or under base catalyzed phase transfer catalysis conditions react with appropiate organic halides to provide corresponding unsymmetrical functionalized organic sulphides.With aqueous sodium hydroxide, thioiminium salts provide the disulphides corresponding to incipient thiol.
