Title: Innovations of Raymond Dagger
Introduction
Raymond Dagger is a notable inventor based in Raleigh, NC (US). He has made significant contributions to the field of chemistry, particularly in the development of catalysts for stereoselective cyclopropanation. With a total of three patents to his name, Dagger's work has implications for various applications in organic synthesis.
Latest Patents
Dagger's latest patents focus on Ruthenium (II) catalysts designed for use in stereoselective cyclopropanations. These chiral ruthenium catalysts comprise salen and alkenyl ligands, which are essential for achieving stereoselectivity in cyclopropanation reactions. The innovative aspect of his work lies in the preparation of the chiral ruthenium catalyst in situ by combining an alkenyl ligand, a deprotonated chiral salen ligand, and a ruthenium (II) metal. A preferred catalyst is created by combining 2,3-dihydro-4-venylbenzofuran, deprotonated 1,2-cyclohexanediamino-N,N'-bis(3,5-di-t-butyl-salicylidene), and RuCl(p-cymene).
