    Description / Table of Contents: Transition Metal Carbyne Complexes, XIII: Syntheses and Properties of mer-Tricarbonylhalogeno(methylcarbyne)(timethylphosphine or -arsine, -stibine)chromium Complexescis-Tetracarbonyl(methoxymethylcarbene)(trimethylphosphine or -arsine, -stibine)chromium(0) complexes react with boron trihalides BX3 (X = Cl, Br, I) under splitting off of the methoxy group and substitution of a CO ligand by a halide ion. In the resulting carbyne complexes the CO groups are meridionally arranged. The halogen atom is trans-positioned to the carbyne ligand. The spectroscopic data of the new compounds are discussed.
    Notes: cis-Tetracarbonyl(methoxymethylcarben)(trimethylphosphin bzw. -arsin, -stibin) chrom(0)-Komplexe reagieren mit Bortrihalogeniden BX3 (X = Cl, Br, J) unter Abspaltung der Methoxygruppe und Substitution eines CO-Liganden durch ein Halogenid-Ion. In den so erhältlichen Carbinkomplexen sind die CO-Gruppen meridional angeordnet, das Halogenatom befindet sich in trans-Stellung zum Carbinliganden. Die spektroskopischen Daten der neuen Verbindungen werden diskutiert.
