Organobridged dicobaloximes: Synthesis and NMR correlation
Gupta,Qanungo, Kushal
, p. 213 - 220 (1997)
Organobridged dicobaloximes of the type Py(L)2CoIII-(CH2)n-CoIII(L)2Py [L = dmgH- and dpgH-, n = 3,4,5,6 and 10] are synthesized by the reaction of CoI(L)2Py 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 1H 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 Pα and the Pγ resonances.
