Nitrogen Attached Directly Or Indirectly To The Hetero Ring By Acyclic Nonionic Bonding Patents (Class 549/467)
  • Patent number: 4605740
    Abstract: The present invention relates to a process for the production of N-substituted acrylic acid amides by conversion of 2-carboalkoxy-t-oxabicyclo(2,2,1)hept-5-enes with primary or secondary amines to 2-carboxamide-7-oxabicyclo(2,2,1)hept-5-enes and the thermal decomposition of the latter, preferably in the presence of Lewis acids and in a vacuum, to furane and N-substituted acrylic acid amides. The process according to the invention results in high purity N-substituted acrylic acid amides that are, in the main, free of bifunctional monomers which would disrupt the subsequent polymerization of the N-substituted acrylic acid amides by undesired cross-linking.

    Abstract: N-chlorosulfinylcarbamate esters are produced by the reaction of thionyl chloride with carbamate esters having one unsubstituted hydrogen on the carbamate nitrogen atom, preferably in the presence of a hydrogen chloride acceptor. The resulting N-chlorosulfinylcarbamate esters are useful intermediates in the preparation of pesticides having relatively low mammalian toxicity.
