Cobalt iodide methoxide

The diffuse reflectance spectrum of cobalt iodide methoxide was rather complex and showed a large charge transfer band in the visible region. However, some discontinuity was observed around 16000 and 18000cm" which was assigned to a 4Ti(P) charge transfer edge. 

Acylcobalt carbonyl derivatives are cleaved by sodium methoxide to esters and sodium salts of the corresponding carbonyl anions. By means of this reaction, acetyl[bis(trimethylolpropane phosphite)]cobalt dicarbonyl has been converted into sodium [bis(trimethylolpropane phosphite)]cobalt dicarbonyl. The latter compound is readily alkylated by methyl iodide to form the methylcobalt derivative and this compound in turn reacts with another mole of the phosphite ester, in the same way that methylcobalt tetracarbonyl does, to form acetyl[tris(trimethylolpropane phosphite)]-cobalt carbonyl ... 

This sequence of reactions may be carried further by cleaving the last product with sodium methoxide and alkylating again with methyl iodide to produce methyl[tris(trimethylolpropane phosphite)]cobalt ...
