Unexpectedly different reactions of [(arene)Mn(CO)3]+ cations (arene = trindane, indane, tetralin, or dibenzosuberane) with potassium t-butoxide - C-H insertions, haptotropic shifts, dimerization, or elimination

[(η6-Trindane)Mn(CO)3][BF4] (1) reacts with tert-BuOK in THF in the presence of alkyl halides (CH2= CHCH2Br, CH3I) to yield the corresponding (η6-C15H18)Mn(

Kinetics and mechanism of substitution reactions of Mn(η5-C9H7)(CO)3 and Mn(η5-C13H9)(CO)3

The reactions of Mn(η5-C9H7)(CO)3 and Mn(η5-C13H9)(CO)3 with phosphines and phosphites proceed readily in decalin at elevated temperatures to form monosubstituted products. For Mn(η5-C13H9)(CO)3 a second substitution takes place with P-n-Bu3 and P-c-Hx31 which proceeds via an η1-fluorenyl species, Mn(η1-C13H9)(CO)3(P-n-Bu 3)2. All these reactions take place by a second-order process, first order in metal complex and first order in nucleophile. Reaction rates depend on both size and basicity of the entering ligand. Substitution reactivity of these compounds contrasts the observed2 thermal substitution inertness of Mn(η5-C5H5)(CO)3. This difference in reactivity is discussed in terms of the indenyl ligand effect of the indenyl and fluorenyl ligands vs. the cyclopentadienyl ligand.

The Indenyl Ligand Effect on the Rate of Substitution Reactions of Rh(η-C9H7)(CO)2 and Mn(η-C9H7)(CO)3

Carbonyl substitution by triphenylphosphine (PPh3) in the indenyl compounds Rh(η-C9H7)(CO)2 and Mn(η-C9H7)(CO)3 proceeds by second order rate law which is first order in complex and first order in PPh3 and in both cases the rates are much faster than for the corresponding cyclopentadienyl complexes; for rhodium a rate enhancement of 108 is found for the indenyl compound over the corresponding cyclopentadienyl compound.
