N,N-dichloro-N-acyl compounds such as N,N-dichlorocarbamates, sulfonamides, amidosulfonamides selectively react with conjugated dienes to yield the corresponding 1,4-adducts, i.e. N-chloro-N-chlorocrotyl compounds. The N-chloro group of these adducts can be selectively reduced by aqueous sodium sulfite. Both the original and reduced adducts are effective fungicides, herbicides and bacteriocides. |
