Cobalt ii halides ketazine and aldezine complexes
Abstract
Abstract COBALT (II) HALIDES COMPLEXES OF THE FORMULA (CO(II) R1-C(-R2)=N-N=(R3=N-N=)NC(-R4)-R5)(X)2 ARE PREPARED WHERE R1 AND R4 ARE HYDROGEN, ALKYL, ARYL HALOARYL, HALOALKYL, ARALKYL, FURYL, TETRAAHYDROFURYL AND R2 AND R5 ARE ALKYL, ARYL, HALOARYL, HALOALKYL, ARALKYL, FURYL, TETRAHYDROFURYL OR R1-C-R2 TOGETHER IS CYCLOALKYL OF AT LEAST 3 CABON ATOMS AND R4-C-R5 TOGETHER IS CYCLOALKYL OF AT LEAST 3 CARBON ATOMS, R3 IS ALKYLENE OR ARYLENE, N IS 0 OR 1 AND X IS HALOGEN. THE COMPOUNDS ARE USEFUL AS DRIERS FOR ALKYD RESINS AND TO ACCELERATE THE OXIDATIVE POLYMERIZATION OF OLEFINIC POLYMER SYSTEM, PARTICULARLY UNSATURATED POLYESTERS, IN CONJUNCTION WITH ORGANIC PEROXIDES. THE COMPOUNDS CAN ALSO BE USED TO FORM MIXED BIDENTATE LIGAND CHELATES AS WELL AS MIXED BIDENTATE UNIDENTATE LIGAND CHELATES OF THE FORMULA (CO(II)(AZ)8Y)M(Z)4-2M)X2 WHERE AX IS R1-C(-R2)=N-N=(R3=N-N=)N-C(-R4)-R5 WHICH HAVE THE SAME USE.
