Abstract
|
|
|
|
3-(N-Alkylamino)-4,5-dihydro-1,2,5-thiadiazole 1,1-dioxides have been prepared by the treatment of 3-imino-1,2,5-thiadiazolidine 1,1-dioxides with alkylamines. The selected spectral properties of these heterocycles are detailed, as well as an X-ray crystallographic structure of a representative member of these compounds. 3-(N-Benzylamino)-4,5-dihydro-4-(4'-methoxyphenyl)-1,2,5-thiadiazole 1,1-dioxide crystallyzes in space group P21/a, monoclinic, with a=22.512(3)(1)Å, b=9.831(2)Å, c=7.194(4)Å, β=96.65(2), and Z=4.
