The new α,ω‐[boryl(organyl)]phosphane o ‐Ph 2 PC 6 H 4 CH 2 B (NMe 2 ) 2 ( 10 ) was obtained in good yields from the reaction of CIB(NMe 2 ) 2 with o ‐Ph 2 PC 6 H 4 CH 2 Li(tmeda). Five derivatives of 10 were obtained by substituting the boron‐bound amino groups by reactions with MeOH, BCl 3 , HCl, and LiAlH 4 , respectively, in particular, o ‐Ph 2 (HCl)PC 6 H 4 CH 2 BCl 2 (HNMe 2 ) ( 10 e ) which shows a unique PHClHN 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 C 6 H 6 was determined by single crystal X‐ray diffraction.
