| 内容記述 | [Synopsis] Palladium complexes are active catalysts in converting salts of N-chloroarylsulfonamides, N-(arylsulfonyl)iodoimines and N-(arylsulfonyl)selenilmines into arylsulfonyl isocyanates which are intermediates in manufacturing sulfonylurea type herbicides. Potassium N-chloroarylsulfonamidates are more advantageous starting materials that the analogous sodium derivatives. Application of acetonitrile as a solvent in the catalytic carbonylation of N-chloroarylsulfonamidates allowed to reduce the catalyst/substrate ratio and the CO pressure as compared to those used with chlorinated hydrocarbons. Palladium complexes with coordinated arylsulfonylnitrene ligands are thought to play a key role in these reactions. | |||||||||||
