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 $P2_1a$, monoclinic, with $a=22.512(3)(1)\AA$, $b=9.831(2)\AA$, $c=7.194(4)\AA$, $\beta=96.65(2)$, and Z=4.
3-Imino-1, 2, 5-thiadiazolidine 1, 1-dioxide와alkylamine 의 반응에 의하여 3-(N-alkylamino)-4, 5-dihydro-1, 2, 5-thiadiazole 1, 1-dioxide를 제조하였다. 이 헤테로고리 화합물의 주요 분광학적 성질과 X-선 결정학외절에 의한 분자구조를밝혔다. 3-(N-benzylamino)-4, 5-dihydro-4-(4'-methoxyphenyl)-1, 2, 5-thiadiazole 1, 1-dioxide의 단결정은 단사정계, 공간군은 $P2_1a$, $a=22.512(3)(1)\AA$, $b=9.831(2)\AA$, $c=7.194(4)\AA$, $\beta=96.65(2)$, 그리고 Z=4이다.
