    Heck arylation of acyclic olefins employing arenediazonium salts and chiral N,N ligands: new mechanistic insights from quantum-chemical calculations

    A quantum-chemical study based on the Kohn–Sham density functional theory (DFT) has been performed in order to investigate the asymmetric Heck–Matsuda (HM) reactions involving a chiral N,N ligand pyrimidine-oxazo...

    DFT exploration of mechanistic pathways of an aza-Morita–Baylis–Hillman reaction

    A new bimolecular pathway for a model aza-MBH reaction is presented and then explored in more details by DFT/M06-2X calculations. For this bimolecular pathway, explicit formic acid was considered in the rate-dete...

    The importance of conformational search: a test case on the catalytic cycle of the Suzuki–Miyaura cross-coupling

    Conformational diversity is an often neglected aspect in computational studies of transition metal complexes, even when relatively large systems are involved. The importance of conformational searches is illus...
