Organometallic Complexes of Indole and Carbazole

Indole and carbazole are characterized by the enhanced Tr-electron density within the six-member cycles, which allows one to predict t) coordination as the preferential coordination route. In contrast to pyrrole, indole, in accord with experimental (62JA2534 64JA3796 71JA5102) and theoretical (82T3693) data, has 

Unusual annulated derivatives of pyrrole, 90 and 91, were found as efficient catalysts for the polymerization of propene (98JA10786). 

Reaction of chromium hexacarbonyl with the derivative of tryptophan yields 99 (R = Me), which is hydrolyzed to 99 (R = H) and transformed into 99 (R = C6H4NO2) when treated with / -nitrophenol and dicyclohexylcarbodiimide [82JOM(240)163]. 

The organomanganese chemistry of indole is primarily characterized by the activation of the pyrrolic counterpart. First of all, this is the coordination, which 

The synthesis of cyclopentadienyliron(T] -indolyl) proceeds through formation of 110 (88PAC1193). Transformation into the T] -complex occurs at elevated temperatures. Carbazole forms only the 7V-carbazolyl complex 111 under these circumstances. However, carbazole with ferrocene and aluminum chloride/aluminum powder gives the iQ -coordinated dication 112 [80JOM(186)265].
