    Description / Table of Contents: Synthese und Reaktionen von {o-{[Bis(dimethylamino)boryl]methyl}phenyl}diphenyl-phosphanDas neue α,ω-[Boryl(organyl)]phosphan o-Ph2PC6H4CH2 (NMe2)2 (10) wurde synthetisiert und spektroskopisch charakterisiert. Die Reaktivität dieser Verbindung, vor allem gegenüber Substitutionsreaktionen am Boratom war der Gegenstand unserer Untersuchungen. Verbindung 10 reagiert mit MeOH, BCl3 bzw. HCl zu den Verbindungen o-Ph2PC6H4CH2B(OMe)2 (10 a), o-Ph2PC6H4CH2BCl2 (10 c), o-Ph2PC6H4CH2BCl2 (HNMe2) (10 d) und o-Ph2P(HCl)C6H4CH2 BCl2(HNMe2) (10 e). Die Umsetzung von 10 a mit LiAlH4 führt zu o-Ph2PC6H4CH2BH2 (10 b). Verbindung 10 e wurde zusätzlich durch eine Röntgenstrukturanalyse charakterisiert.
    Notes: The new α,ω-[boryl(organyl)]phosphane o-Ph2PC6H4CH2B (NMe2)2 (10) was obtained in good yields from the reaction of CIB(NMe2)2 with o-Ph2PC6H4CH2Li(tmeda). Five derivatives of 10 were obtained by substituting the boron-bound amino groups by reactions with MeOH, BCl3, HCl, and LiAlH4, respectively, in particular, o-Ph2(HCl)PC6H4CH2BCl2 (HNMe2) (10 e) which shows a unique P—H—Cl—H—N unit. Compound 10 and its derivatives were characterized by multinuclear NMR methods, mass spectra, and elemental analyses. In addition, the structure of 10 e · 1.5 C6H6 was determined by single crystal X-ray diffraction.
