MACROCYCLIZATION OF TRANSITION METAL COMPLEXES OF ALPHA-FURILGLYOXIME AND BENZILGLYOXIME

Abstract
The α-furil- and benzilglyoximates of nickel (II), palladium(II), platinum(II), cobalt(III), rhodium(III) and rhenium(III) have been prepared in a crystalline state and the corresponding macrocycles obtained by reaction with BF3·OE2 utilizing the metal ion as a template. The planar glyoximates yielded macrocycles whereas the macrocyclization of octahedral complexes could not be accomplished. The reactions and the predicted structures have been compared with known structures.
