199Hg hyperfine coupling in the e.s.r. spectra of mercurated arene radical cations: evidence for an alternative mechanism of mercuration
Abstract
The mercuration of various arenes is promoted when they are photolysed in trifluoroacetic acid containing mercury(II) trifluoroacetate, and 199Hg hyperfine coupling can be observed in the e.s.r. spectra of the radical cations which are formed.
