Article abstract of DOI:10.1246/cl.1997.855

Novel bis(2,6-dimesityl-4-methylphenyl)phosphaarsene was synthesized by the coupling reaction of 2,6-dimesityl-4-methylphenylphosphine with dichloro(2,6-dimesityl-4-methylphenyl)arsine in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene and isolated as stable crystals. The radical anion generated by the sodium metal reduction of the phosphaarsene was investigated by X-band EPR.
