deals with azodyes naturalisedthroughglycoconjugation with a very common saccharide – lactose – and with its galactose and glucose components. The conjugation takes place through a bifunctional linker, here a terminal dibromoalkane, so the final products are very stable diether derivatives of the starting dyes. These transformations produce naturaliseddyes – indeed, water-soluble and multipurpose

of alkenes, alkynes, 1,3-enynes, and [1.1.1]propellane with dithiosulfonates. The resulting dithiosulfonylated styrene is an excellent nucleophilic disulfuration reagent, which can react with a variety of electrophiles to accessunsymmetricdisulfides efficiently.
