α-Funktionelle 2-Methylphenylphosphane, 2-(HE?CH2)?C6H4?PH2 (E = O,NR, PH). II. Komplexbildungsverhalten mit den Metallcarbonylen des Cr,Mo, W

α-Functionalized 2-Methyl Phenylphosphines, 2-(HE? CH₂)? C₆H₄? PH₂ (E = O, NR, PH) II. Coordination Behaviour with Metal Carbonyles of Cr, Mo, W The preparation of different carbonyl substituted coordination compounds (M: Cr, Mo, W) of the phosphines 2-(HE? CH₂)C₆H₄? PH₂ (E = O, NPh, PH) is described. In one case, after deprotonation of a PH₂ group a phosphine/phosphide migration of a W(CO)₅ fragment is detected.
