Procedure

The iodide from Example XX (8.2 g, 0.023 mol) and triphenylphosphine (10 g, 0.038 mol) were dissolved in benzene (70 ml). The solution was boiled with stirring for 16 hours. After cooling, the benzene layer was decanted and the viscous residue was dissolved in a little acetone. Addition of ether gave 5.01 g (35% by weight yield) of a crystalline product, melting point 102°-104° C., while dilution of the mother liquor with ether gave a further 6.0 g (42% by weight yield) of less pure product (oil).
