TRIDENTATE LIGANDS AND RELATIVE COMPLEXES WITH TRANSITION METALS

摘要

A description follows of ligands having general formula (I) wherein R1, R2, R3, R4, R5, and R6, the same or different, are selected form hydrogen, halogen, C1-C10 alkyl, C6-C15 aryl optionally halogenated, or adjacent pairs of Ri groups (with i ranging from 1 to 6) are bound to each other to give cyclic hydrocarbon structures condensed with the thiophene or pyridine ring; R7 is selected from H, C1-C10 alkyl, C6-C15 aryl; R8 is selected from C1-C10 alkyl and C6-C15 aryl. The complexes of the above ligands with transition metals are also described.
