Abstract :A series of new electron rich olefins insert ignore into journalissuearticles values(=\overset{|} CNRinsert ignore into journalissuearticles values(CH2);4\overset{|}NR);2, 3, insert ignore into journalissuearticles values(a; R = CH2C6H5, b; R = CH2C6H4-OMe-p, c; R = CH2C6H4-NMe2-p); was generated via the condensation of RNHinsert ignore into journalissuearticles values(CH2);4NHR with Me2NCH insert ignore into journalissuearticles values(OMe);2. The C=C bond cleavage reactions of 3 with S8 and Se provide a simple and straightforward method for the synthesis of 1,3-diazepan-2-chalcogenones 4 and 5, respectively.
