FIELD: chemistry.
SUBSTANCE: described is a novel method of producing non-metal tetraazachlorins of general formula 
or 
or 
R2=R3=R4=R5=H, Br, CI; R3=R4=R5=H, R2=NO2, PhSO2, PhS; R2=R4=R5=H, R3=NO2, PhSO2, t-Bu; R2=R5=H, R3=R4=PhS; by mixed condensation of tetramethylsuccinonitrile (TMSN) with corresponding 1,2-dinitriles of unsaturated aliphatic or aromatic acids in the presence of indium chloride, with molar ratio TMSN:dinitrile:indium chloride of 1-5:1:1 and catalytic amounts of ammonium molybdate in quinoline at 230-238°C, followed by demetallisation of the intermediate indium complexes with hydrochloric acid.
EFFECT: method considerably increases output of end products.
