    Description / Table of Contents: Transition Metal Carbene Complexes, LXVI. Pentacarbonyl[methyl(methylseleno)carbene] Complexes of Chromium(0) and Tungsten(0) and Pentacarbonyl{trimethylphosphine[methyl(methylseleno)methylene]}tungstenPentacarbonyl(methylmethoxycarbene)chromium(0) and -tungsten(0) react with pure methylselenol with cleavage of methanol to give pentacarbonyl[methyl(methylseleno)carbene]chromium(0) and -tungsten(0). The latter one yields the corresponding pentacarbonyl{trimethylphosphine[methyl(methylseleno)methylene]}tungsten with trimethylphosphine at low temperatures. The structures of the thermolabile compounds were ascertained by their spectra.
    Notes: Pentacarbonyl(methylmethoxycarben)chrom(0) und -wolfram(0) reagieren mit reinem Methylselenol unter Abspaltung von Methanol zu Pentacarbonyl[methyl(methylseleno)carben]chrom(0) bzw. -wolfram(0). Letzteres setzt sich mit Trimethylphosphin bei tiefen Temperaturen zum entsprechenden Pentacarbonyl{trimethylphosphin[methyl(methylseleno)methylen]}wolfram um. Die Strukturen der thermolabilen Verbindungen wurden spektroskopisch gesichert.
