Organobridged dicobaloximes: Synthesis and NMR correlation
摘要:
Organobridged dicobaloximes of the type Py(L)(2)Co-III-(CH2)(n)-Co-III(L)(2)Py [L = dmgH(-) and dpgH(-), n = 3,4,5,6 and 10] are synthesized by the reaction of Co-l(L)(2)Py with the corresponding alkyl dihalides. A mixture of haloalkylcobaloximes and the dicobaloxime is formed in each reaction. The purification procedure for the dicobaloxime is established. A comparison of 'cis influence' due to the equatorial ligands in the haloalkyl and the dicobaloximes by H-1 NMR reveals that the extent of the cis influence on the Co-CH2 resonance is more in the case of the dicobaloxime but it is nearly same for the P-alpha and the P-gamma resonances.
