Abstract: Process for producing biaryl compounds by aerobic cross dehydrogenative coupling (CDC) of two arene groups comprising at least one aryl carbon-hydrogen bond, in the presence of a catalyst system comprising a palladium salt comprising at least one non-cyclopalladatable carboxylate anion and one or more non-beta-eliminatable, non-cyclopalladatable ligands comprising at least one N-donor atom, the one or more ligands having a 0.5/1-1.5/1 molar ratio of N-donor atoms relative to the Pd atoms.

Abstract: The present invention relates to a process for the deprotection of protected amine compounds, wherein the protected amine compound is contacted with an electrophilic oxidating agent that is optionally formed in situ, said electrophilic oxidating agent being selected from the group of I2, Br2, Cl2 and compounds comprising a halogen atom having a formal oxidation state of 1+, 3+, 5+ or 7+, provided that the electrophilic oxidating agent is not iodobenzene diacetate. The process can be conveniently employed in the synthesis of 1,3-amino alcohols, ?-amino acids and heterocyclic compounds, in particular ?-amino acids.
