Abstract

Abstract: The activation of various aromatic hydrocarbons by mercuration and thallation proceeds via*-complexes, as observed by the transient charge-transfer (CT) absorption spectra. Quantitative spectrophotometric analysis of (a) the association constants K and (b) the second-order rate constants k2 establishes the reactive forms of the electrophiles to be Hg (02CCF3), and T1 (02CCF3) 2+, both in*-complex formation as well as in aromatic ...
