Diazo transfer to β-keto sulfoxides to form stable isolable α-diazo-β-keto sulfoxides has been achieved for the first time. Both monocyclic and benzofused ketone derived β-keto sulfoxides were successfully explored as substrates for diazo transfer. Use of continuous flow leads to isolation of the desired compounds in enhanced yields relative to standard batch conditions, with short reaction times, increased safety profile, and potential to scale up.

The title compound, 3-(4-methoxy-benzylidene)-isothiochroman-4-one (C 17H14O2S) was prepared from the reaction of isothiochroman-4-one with benzaldehyde in the presence of small amount of HCl. The structure of the synthesised compound was determined by IR, 1H NMR and X-ray crystallography. The structure was solved in monoclinic, space group P21/n with a = 3.9773 (7) A, b = 10.918 (2) A, c = 30.609 (6) A, β = 90.615 (3)°, V = 1329.1 (4) A3, Z = 4 and with R int = 0.047. The bicyclic ring of isothiochroman-4-one moiety does not adopt a planar geometry. The molecular conformation is stable via C10-H???O1 and C16- H???S1 intramolecular hydrogen-bonding interactions. These contacts involve molecules in an extended two-dimensional sheet to the bc plane.
