Arenediazonium o-benzenedisulfonimides can be used as new and efficient reagents for Heck-type arylation reactions of some common substrates containing C–C multiple bonds, namely ethyl acrylate, acrylic acid, acroleyne, styrene and cyclopentene. The reactions were carried out in an organic solvent, in the presence of Pd(OAc)2 as pre-catalyst, and gave rise to arylated products, for example, ethyl cinnamates
spectra have been recorded for all the synthesized salts; the data are in good agreement with the rather limited published data and constitute a first extensive report of 13C-NMR chemical shifts in diazoniumsalts. An excellent linear relationship emerged between Brown's substituent constants s+p and the 13Cipso chemical shifts. The diazoniumsalts obtained proved to be much more soluble in organic
Olefins could be arylated in good yields by the combination of arylamines (substituted anilines: 4-Me, 4-Cl, 4-Br, 2-NO2, 4-NO2, and 3-aminopyridine) and t-butyl nitrite under palladium(0) catalysis.
