ABSTRACT:
N,N-dichloro-N-acyl compounds, such as N,N-dichlorocarbamates, sulfonamides and 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 the reduced adducts are novel compositions useful as biologically active compounds and vulcanizing agents. The bis-N-chlorocrotyl carbamates and their N-chloro derivatives are particularly claimed compositions.
