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.

Some 3-trimethylsilyl-2-thiabicycloheptenes and heptanes of known configuration were protiodesilylated and the stereochemistry of the reaction was studied.Evidences for a carbanionic intermediate as well as the pivotal role played by the metal coun
Transformation of Thiosulphonates into α-Sulphonyldisulphides, a New Class of Thioaldehyde Precursors

Toluene-p-thiosulphonates, RCH2SSO2Tol (1) where R is an electron-withdrawing group, are transformed readily into α-sulphonyldisulphides (2) which, with triethylamine, undergo fragmentation-elimination to give 2 moles of thioaldehydes, RCHS.
