摘要

A simple synthesis of 1,2-bis(2,6-dimethylphenylphosphino)ethane is reported. Synthesis involves reaction of in situ prepared lithium salt of 2-bromo-m-xylene with 1,2-bis(dichlorophosphino)ethane in diethylether. The title compound, C34H40P2, crystallized in the triclinic space group, P-1 with cell parameters: a = 6.977(5) b = 9.186(5) c = 11.629(5) angstrom, alpha = 109.880(5) beta = 92.993(5) gamma = 94.362(5)degrees, V = 696.4(7) A(3), Z = 1. The compound has been characterized by NMR and single crystal X-ray crystal structure analysis and the purity was confirmed by elemental analysis. The solid state data were also calculated by DFT. Graphic A simple synthesis and structure of 1,2-bis(2,6-dimethylphenylphosphino) ethane, an important but missing member of the phosphine ligand family is reported.
