Manganese Alkyls and Hydrides

Synthesis and Reactivity of New Cyclomanganated (η6-Arene)tricarbonylchromium Complexes

“…The first one would entail a simple oxidative addition onto the manganese center that would lead to a very reactive hydrido−Mn(III) complex (path 1, Scheme ) 2b…”

“…In the very wide field associated with intramolecular C−H activation, also referred to as the cyclometalation reaction, the chemistry of cyclomanganated compounds is one of the most documented in the literature …”

“…Several authors have studied the reaction between alkylpentacarbonylmanganese complexes, e.g. R−Mn(CO) 5 , and various aromatic substrates bearing thioether, amino, or ketone functions 2c-e However, even though widely applied and used, the cyclomanganation reaction has received less attention from a mechanistic point of view …”

Reaction of Organolithium Reagents with Tetracarbonyl[2-(phenyl-κC2‘),pyridine-κN]rhenium(I): Isolation and Structural Characterization of Acyl Rhenate Species

“…1 Many examples of aromatic substrates are known to undergo a cyclometalation reaction when reacted with alkylpentacarbonylmanganese or -rhenium complexes under thermal conditions. 2 Cyclomanganated aromatics display a smaller spectrum of reactivity than other families of cyclometalated arenes. 3 Indeed, most of the reactions reported to take place with cyclomanganated complexes deal with photochemically or thermally promoted insertion reactions of unsaturated hydrocarbons or inorganic molecules.…”

Novel tridentate diamino organomanganese(II) complexes as homogeneous catalysts in manganese(II)/copper(I) catalyzed carbon–carbon bond forming reactions

“…The proposed monomeric structure of 3 would resemble that of analogous [Sn II R(NCN)] complexes [11]. However, aggregate structures are also feasible, as shown by examples of organomanganese complexes in which organic groups are bridging two Mn centers [12]. In species of general formula [MnR(NCN)], the R group could be involved in the latter kind of binding, in addition to the NCN ligand [13], e.g.…”
