The formation of 10,10′(5H,5′H)-spirobiphenophosphazinium chloride by the interaction of diphenylamine and phosphorus trichloride
Abstract
The interaction of diphenylamine and phosphorus trichloride at 210° followed by treatment of the reaction mixture with water yields not only the known 5,10-dihydrophenophosphazine 10-oxide but also the novel compound, 10,10′(5H,5′H)-spirobiphenophosphazinium chloride.
