Reaktive ?-Komplexe der elektronenreichen Uebergangsmetalle; VI. Katalysche und stoechiometrische Reaktionen von ?-Aren-Eisenkomplexen mit Alkinen

The reactive ?-arene complexes bis(ethene)(toluene)iron, (toluene)(1-methylnaphthalene)iron, and bis(tolueneiron)cyclooctatetraene are catalysts for the cyclotrimerization of alkynes RCCR' (R,R' = H, CH3, C2H5, t-C4H9, C6H5, COOCH3) to benzene derivatives.When R = R' = Si(CH3)3, CH2OH or COOH the reaction fails.In the case of bis(ethene)(toluene)iron and acetylenedicarbonic acid dimethylester a cycloaddition of two alkynes and one ethene takes place.When the primary products of the catalytic reaction were trapped with trialkylphosphite, complexes of the type tris(trialkylphosphite)(alkyne)iron and trisbis(trimethylphosphite)diiron, become readily accessible.
