Ligand Dependent Regioselectivity in Palladium Mediated Allylic Alkylation
In this thesis, different aspects on ligand dependent regioselectivity in palladium mediated allylic alkylation have been studied. It is believed that the regioselectivity is a result of nucleophilic attack trans to phosphorous when applying ligands wih different donor atoms. The regioselective …
