PROCESS FOR THE ORTHOALKYLATION OF EVENTUALLY ALKYL-SUBSTITUTED META-PHENYLENEDIAMINES

m-Phenylenediamines are alkylated in the orthoposition by heating them with an Al/Zn alloy and aluminium chloride, and reacting them with lower alkenes at elevated pressures and temperatures when the evolution of hydrogen is complete.
