R' is selected from hydrogen, alkyl, alkoxy, amino, carbocylic or heterocyclic. R" is selected from hydrogen, alkyl, aryl, heteroaryl, alkenyl, alkynyl, alkoxy, aryloxy, amino, halogen, cyano, nitro, trifluoromethyl, imino, azo, carboxy ester or amide or is a carbocyclic or heterocyclic group fused to the moiety.
