I. Foch et al., Reaction of [Pd2Cl2(mu-dppm)(2)] with arenesulfonyl azides. Kinetics and mechanism of formation of arenesulfonylimido-bridged A-frame adducts, INORG CHEM, 38(17), 1999, pp. 3944
Substituted arenesulfonyl azides react with [Pd2Cl2(mu-dppm)(2)] in an entr
opy-controlled electrophilic process, affording an imido-bridged A-frame ad
duct via N-2 extrusion. The Hammett relationship is valid for the 4-substit
uents.
