A new method of synthesis of η5-pyrrolyltricarbonylmanganese(I) is reported, along with the first syntheses of η5-indolyltricarbonylmanganese(I) and of η5-1-pyrindinyltricarbonylmanganese(I).Kinetic studies on CO substitution reactions of these η5-N-heterocyclic manganese carbonyls show that the reactions take place by a second-order process, first-order in metal complex and first-order in nucleophile.The most significant observation is that the N-heterocyclic compounds react faster than do their carbocyclic counterparts.This anticipated result is consistent with the greater electron-withdrawing ability of the N systems in the transition state for reaction, because N is more electronegative than is C.
