TRIDENTATE LIGANDS AND RELATIVE COMPLEXES WITH TRANSITION METALS

摘要

A DESCRIPTION FOLLOWS OF LIGANDS HAVING GENERAL FORMULA (Ι) WHEREIN R1,R2,R3,R4,R5 AND R6,THE SAME OF DIFFERENT ,ARE SELECTED FROM HYDROGEN,HALOGEN,C1-C10 ALKYL,C6-C15 ARYL OPTIONALLY HALOGENATED,OR ADJACENT PAIRS OF R1 GROUPS (WITH i RANGING FROM 1 TO 6 )ARE BOUND TO EACH OTHER TO GIVE CYCLIC HYDROCARBON STRUCTURE CONDENSED WITH THE THIC-PHENE OR PYRIDINE RING; R7 IS SELECTED FROM H,C1-10 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.
