Abstract

Abstract The starting material chlorodi (o-tolyl) phosphine has been prepared by the reaction of phosphorus trichloride and the Grignard of o-chlorotoluene. The intermediate lithium di (o- tolyl) phosphide was obtained by the direct reaction of lithium metal and chlorodi (o-tolyl) phosphine in tetrahydrofuran. Lithium di (o-tolyl) phosphide reacted smoothly with ω, ω'- dihaloalkanes, X (CH 2) n X (n 1-4, 6, 8, X Cl or Br) to form the tertiary diphosphines (o- ...
