Process for the synthesis of sulfonyl halides and sulfonamides from sulfonic acid salts |
| abstract |
The present invention provides synthetic processes for the preparation of sulfonyl halides of Formula Ar- (R) 2-SO2-X and sulfonamides of Formula Ar-(R)2-SO2- NR4R5, where the constituent variables are as defined herein, that are useful as intermediates in the preparation of pharmaceuticals. The sulfonyl halides are prepared by reacting a sulfonic acid salt with a halogen substitution reagent in the presence of a catalytic amount of water and in the presence of a co-catalyst . The so prepared halides can than be further reacted with an amine to obtain the sulfonamides. |
