Cyclopalladated imine catalysts in Heck arylation: search for the catalytic speciesElectronic supplementary information (ESI) available: selected spectroscopic data for 1d, 2a and 2b. See http://www.rsc.org/suppdata/cc/b0/b004502k/
Abstract
The application of the new cyclopalladated imine complexes of
the Milstein-type 1d, 2a and 2b and the immobilised derivative 2c in the
Heck reaction has provided evidence that these complexes are unstable and
the active species is metallic
