Cyclic or arene π systems are either actor or spectator ligands that typically bind to metals through more than 2 atoms. The bonding is similar to that of the linear π systems, consisting of a more typical bond formed by the donation of electron density from the π orbitals of the ligand to the dσ of the metal, and back donation from …
WebIntroduction. In collaboration with DSM, we are pleased to offer a range of MonoPhos ™ ligands for the research market. † Feringa and co-workers have invented a diverse array of these chiral, monodentate phosphoramidites based on the privileged BINOL platform. 1 The MonoPhos ™ family has exhibited high levels of enantiocontrol in synthetic … Webligands by formal substitution at phosphorus† Sven Roediger, Sebastian U.
