SYNTHESIS AND REACTIONS OF (O-([BIS(DIMETHYLAMINO)BORYL]METHYL)PHENYL)DIPHENYLPHOSPHANE

摘要

The new alpha,omega-[boryl(organyl)]phosphane o-Ph2PC6H4CH2B(NMe2)(2) (10) was obtained in good yields from the reaction of ClB(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-Ph-2(HCl)PC6H4CH2BCl2(HNMe2) (10e) 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 10e . 1.5 C6H6 was determined by single crystal X-ray diffraction. [References: 14]
