Aminecyclopentadienyltungsten Carbonyls and Manganesetungsten Bonded Carbonyls

Abstract

Amines like benzylamine, piperidine and morpholine reacted with π-cyclopentadienyltungsten tricarbonyl dimer, [π-C₅H₅W(CO)₃]₂, and yielded amine derivatives, [(π-C₅H₅)₂W₂(CO)₅Am](Am═C₆H₅CH₂NH₂, C₅H₁₁N, C₄H₉NO). These amine derivatives were reduced with sodium amalgum (Na/Hg) and further reacted with [Mn(CO)₅Br] thus producing Mn-W (manganese-tungsten) bonded carbonyls, [(π-C₅H₅)W(CO)₂Am]^–-[Mn(CO)₅]⁺. All the six compounds are characterised by elemental analysis and IR spectra.
