摘要

The phosphorus ylides (IV) prepared by the new method are stable greenish white solids which can be recrystallized conveniently from hydrocarbons and from ethyl acetate. The structures of the products as phosphoranes (IV) are assigned from their infrared absorptions (Table I) for nitro (6.48-6.51 p) 4 and phosphoranocarbonyl (6.13-6.23 p) groups and from
