Application of 5931-53-3, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.5931-53-3, Name is Diphenyl(o-tolyl)phosphine, molecular formula is C19H17P. In a patent, introducing its new discovery.
Synthesis and reactions of {o-{[bis(dimethylamino)boryl]methyl}phenyl}diphenylphosphane
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-Ph2(HCl)PC6H4CH2BCl 2(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¡¤1.5C6H6 was determined by single crystal X-ray diffraction.
