Answer to Question #177293 in Inorganic Chemistry for Good

Question

The reaction of [(h6-C6H6)Rh(CO)2]+ with CO in the solid-state produces [Rh(CO)4]+. The authors state that neither CpRh(CO)2 nor Cp*Rh(CO)2 reacts in this fashion. Discuss why

Answer 1

There is no substantial isotope effect is seen in the reactions of CpRh(CO). The photochemistry of Cp*Rh(CO)2 in liquid krypton is probed examining the mechanism of photochemical ligand substitution.
