1. The catalytic activity of PdCl2 in the synthesis of aromatic diisocyanates by carbonylation of dinitro compounds depends on the presence of an organic base (pyridine) and a transition-metal oxide in the reaction system, and on the temperature and pressure. 2. The oxides V2O5 and MoO3 activate the PdCl2-pyridine catalyst, the oxides of Sc, Cr, Mn, and Ni reduce the yield of diisocyanates, and Co3O4, and CuO inhibit their formation. 3. The yield of aromatic diisocyanates in the presence of Pd catalysts increases with increasing CO pressure and passes through a maximum at 190–200°C.
