Synthesis of New 1λ 6 ,2,6‐Thiadiazines by Condensation with S , S ‐Dialkylsulfur Diimides Reactions of ketene mercaptals 1a, b, d with S , S ‐dialkylsulfur diimides 2a – c lead to colourless 1λ 6 ,2,6‐thiadiazines 4a – i ; reaction of 1c with 2a – c leads to ring‐open products 3a – c . 5‐Methyl‐substituted 1λ 6 ,2,6‐thiadiazines 6a , c , d can be prepared by condensation of S , S ‐dialkylsulfur diimides 2a , c , d with acrylic acid derivative 5 .
