Abstract: A NEW COMPOSITION OF MATTER HAVING THE FORMULA

PDL(CO)X2

WHERE L IS A LEWIS BASE AND WHERE X IS A HALOGEN. THIS COMPOSITION IS PREPARED BY REACTING CARBON MONOXIDE WITH A LEWIS BASE AND A PALLADIUM-CONTAINING MATERIAL SELECTED FROM THE GROUP CONSISTING OF (A) PALLADIUM DIHALIDE (B) A MIXTURE OF ELEMENTAL PALLADIUM WITH AN ACID HALIDE, AND (C) MIXTURES THEREOF, IN THE PRESENCE OF A LIQUID REACTION MEDIUM. THE RESULTING COMPLEX IS USEFUL AS A CATALYST IN THE PREPARATION OF ORGANIC ISOCYANATES BY REACTING CARBON MONOXIDE WITH AN ORGANIC NITRO COMPOUND. THE LEWIS BASE IS A HETEROAROMATIC NITROGEN COMPOUND HAVING A HETEROAROMATIC RING WHICH CONTAINS (A) 5 OR 6 MEMBERS IN THE RING, (B) ONLY NITROGEN AND CARBON IN THE RING, (C) NO MORE THAN 2 NITROGENS IN THE RING, AND (D) AT LEAST 2 DOUBLE BONDS IN THE RING. TYPICAL HETEROAROMATIC NITROGEN COMPOUNDS INCLUDE PYRIDINE AND ISOQUINOLINE.

Abstract: THE PROCESS FOR PREPARING AN ORGANIC ISOCYANATE BY REACTING AN ORGANIC NITRO COMPOUND WITH CARBON MONOXIDE IN THE PRESENCE OF A CATALYST SYSTEM COMPRISED OF A PALLADIUM COMPLEX OF A LEWIS BASE AND A UNIVALENT ANION. THE LEWIS BASE IS PREFERABLY A HETEROAROMATIC NITROGENCONTAINING COMPOUND CONTAINING BETWEEN FIVE AND SIX MEMBERS IN THE RING, CONTAINING NO ELEMENT OTHER THAN NITROGEN AND CARBON IN THE RING, CONTAINING NO MORE THAN TWO NITROGEN ATOMS IN THE RING, AND HAVING AT LEAST TWO DOUBLE BONDS IN THE RING SUCH AS PYRIDINE AND ISOQUINOLINE. THE UNIVALENT ANION IS PREFERABLY NCS-, N3-, NCO-, AND CN-. THE CATALYST SYSTEM MAY ALSO INCLUDE A SECOND COMPONENT SUCH AS MOLYBDENUM TRIOXIDE OR ANOTHER METAL OXIDE.
