We explored the formation of active palladium catalyst species by degradation of Pd-acetate dimer {with the|using the|with all the|together with the} addition of phosphine ligands (PH3 and PPh3 ) withan automated reaction search employing Density Functional Theory calculations followed by kinetic {studies|research} with stochastic simulation {analysis|evaluation}. Our reaction search {starting|beginning} from dimeric {form|type|kind}, {considered|regarded as|deemed|regarded|viewed as|thought of} a resting state {of the|from the|in the|on the|with the|of your} catalyst, {produced|created|made|developed} {similar|comparable|equivalent|related} monomeric species by sequential ligand addition as {found|discovered|identified|located} {in the|within the|inside the} experimental investigation {of the|from the|in the|on the|with the|of your} active catalytic species in Heck reactions. We analyzed the bonding {in the|within the|inside the} Pd-acetate dimer {and the|and also the|as well as the|along with the|plus the} {role|function|part} of Pd {in the|within the|inside the} stability {of the|from the|in the|on the|with the|of your} dimeric species.
