    Abstract: The invention comprises compounds of formula wherein R1 is Cl, NO2, Ph-N = N-, carboxylic ester or sulphonamido, R2 and R3 are H, halogen, NO2, alkoxy, alkyl or carboxylic ester (up to C4), R4 is H, Cl, alkoxy, alkyl or carboxylic ester (up to C4) and R5 is NO2 or carboxylic ester. These compounds, as well as p-chloroazo compounds generally, are made by reacting p-hydroxyazo compounds with COCl2 in an inert organic solvent in presence of an N,N-disubstituted carboxylic amide.ALSO:Pesticidal compounds have the formula wherein R1 is Cl, NO2, Ph-N=N-, carboxylic ester or sulphonamido, R2 and R3 are H, halogen, NO2, alkoxy, alkyl or carboxylic ester (up to C4). R4 is H, Cl, alkoxy, alkyl or carboxylic ester (up to C4) and R5 is NO2 or carboxylic ester.
