Abstract

Thc reaction between phenyldichloroarsinc and phcnylarsenoxide to give arsenious oxide and diphenylchloroarsine has .been found to be catalysed by a number of materials, notably iron, ferric chloride, zinc chloride and zinc oxide. The last is both the most convenient and most active, and in glass 0.1%, permitted a reduction of the reaction temperature from 240Β°c. to 200Β°c. and the time from 4‐2 hours compared with that of the uncatalysed condensation of 50/50 mixtures, In mild steel reactors with 0.1% of zinc oxide the temperature could be reduced to 140Β°c. and under these conditions it was possible to use the stoichiometric ratio of reactants.

## Abstract Primary nitro compounds have not been employed as nitrile oxide precursors in reactions with active methylene compounds because the reagents commonly used as dehydrating agents also react with these dipolarophiles. However, the Cu^II^‐catalysed cycloaddition/condensation procedure has b
