Abstract
A bis(tosyl)amidoruthenium(III) complex of 1,4,7-trimethyl-1,4,7-triazacycl ononane (Me(3)tacn) is prepared, and its crystal structure revealed the two tosylamido ligands in a cis configuration; the '[Ru-III(Me(3)tacn)(NHTs)(2 )(OH)] + Ag(I) or PhINTs' protocol can effect amidation of saturated C-H bo nds, and an electrophilic tosylimidoruthenium intermediate is implicated ba sed on Hammett correlation studies and trapping experiments.
