Design of reactive organometallic complexes

WebA number of such complexes have been more extensively studied and indeed found greater clinical acceptance as anticancer agents. Recently, developments in coordination chemistry have allowed the design of complexes with well-defined 3-dimensional structures but in which the metal acts as a structural template rather than a reaction centre. WebOrganometallics. A second research area in the Sanford laboratory focuses on the design, synthesis, and reactivity studies of high valent group ten organometallic complexes (e.g., Pd(IV), Ni(III), Ni(IV) complexes).
