Reaction of tetracyanoethylene with SCL2: New molecular rearrangements
(2000)The chloride ion catalysed addition of SCl2 to TCNE gives the dicyanomethylene-1,2,6-thiadiazine 3 as major product together with two unexpected minor products, pyrimidine 4 and pyrroloimidazothiadiazine 5, whose X-ray ...

Substitution at C-4 in 3,5-disubstituted 4H-1,2,6-thiadiazin-4-ones
(2012)3,5-Diaryl-4H-1,2,6-thiadiazin-4-ones react with NaBH 4 to give the 3,5-diaryl-4H-1,2,6-thiadiazin-4-ols and with MeLi to give 4-methyl-3,5-diaryl-4H-1,2,6-thiadiazin-4-ols. The latter dehydrate with p-toluenesulfonic acid ...

Synthesis of asymmetric 3,5-diaryl-4H-1,2,6-thiadiazin-4-ones via Suzuki-Miyaura and Stille coupling reactions
(2012)Asymmetric 3,5-diaryl substituted 4H-1,2,6-thiadiazin-4-ones can be prepared from 3,5-dichloro-4H-1,2,6-thiadiazin-4-one (1) via a multi-step protocol: selective nucleophilic mono-chloro substitution gives either the ...
