A new type of ligand-free Ni-nanoparticles supported on rGO (size distribution average d = 9 ± 3 nm) was prepared and fully characterized via morphological (Fe-SEM), structural (P-XRD, HR-TEM), and spectroscopic (ICP-EOS, XPS) analysis tools. The metal composite was effectively employed in the unprecedented heterogeneously Ni-assisted cross-coupling reaction of aryl/vinyl iodides and thiocarboxylates. A range of sulfur-containing aryl as well as vinyl derivatives (15 examples) was achieved in high yields (up to 82%), under mild reaction conditions, and with wide functional group tolerance.

The reaction between dry arenediazonium o-benzenedisulfonimides (1) and sodium thioacetate or thiobenzoate in anhydrous acetonitrile at room temperature is an efficient and safe procedure, of general validity, for the preparation of S-aryl thiol esters. The products can be easily purified and the yields are always very high. Of the 28 considered examples, the average yield of the S-aryl thioacetates (7) was 86% and that of the S-aryl thiobenzoates (8) 88%. It was possible to recover, in good amount and from all the reactions, o-benzenedisulfonimide (9), reusable for the preparation of salts 1.
