An unprecented N- and C(3)-dialkylation of unactivated amines by a cascade reaction via borrowing hydrogen methodology using new (arene)ruthenium(II) complexes featuring phosphinosulfonate ligands is described. This reaction is highly regioselective and produces water as the only side product.
This invention relates to new fluorescent chemical entities that are designed to attach to biocompatible molecules to form in vivo optical imaging agents.
