Sažetak
Cyclometallation is one of the simplest and most common methods for creating a metal-carbon (M–C) bond and represents a very mild route for activating strong and unreactive a carbon-hydrogen (C–H) bond with transition metals.1, 2 Such reactions produce organometallic compounds with the chelate rings, termed metallacycles, containing the M–C bond and one or two metal-donor bonds. Palladacycles are one of the most popular and investigated classes of cyclometallated compounds due to their extensive application in organic synthesis, catalysis, photochemistry and in the design of new metallomesogenes and bioactive compounds.2, 3 Although a number of synthetic studies of cyclopalladated azobenzenes have been reported, 2, 3 a direct experimental proof for the mono- or dicyclopalladation mechanism of azobenzenes with palladium(II) acetate is still lacking. Here, we describe for the first time a comparative kinetic study of the reaction of Pd(OAc)2 with asymmetrically substituted azobenzenes: methyl orange (MO) and 4'-dimethylamino-4-nitroazobenzene (DN) in DMF. All reactions were followed by 1H NMR spectroscopy measuring intensities for several types of signals.
