Catalytic carbonylation of aromatic nitro compounds in the presence of organic carbonates |
| abstract |
IN THE PROCESS FOR PREPARING AN ORGANIC ISOCYANATE BY REACTING AN ORGANIC NITRO COMPOUND WITH CARBON MONOXIDE IN THE PRESENCE OF A CATALYST, IMPROVED YIELDS OF THE ORGANIC ISOCYANATE ARE OBTAINED AND CONTAMINATION OF THE ISOCYANATE BY PRODUCTS DERIVED FROM ORTHO-DINITRO COMPOUNDS IS SUPRESSED WHEN THE REACTION IS CARRIED OUT IN THE PRESENCE OF AN ORGANIC CARBONATE. IN ADDITION, WHEN THE CATALYST IS A NOBLE METAL HALIDE COMPLEX OF LEWIS BASE SUCH AS PYRIDINE OR ISOQUINOLINE, DECOMPOSITION OF THE CATALYST COMPLEX IS DIMINISHED. |
