Several critical geometries associated with the rearrangement of $CH_3SNO_2\;to\;CH_3SONO$ are calculated with the density functional theory (DFT) method and compared with those of the ab initio molecular orbital methods. There are two probable pathways for this rearrangement, one involving the transition state of an oxygen migration and the other through the homolytic decomposition to radicals. The reaction barrier via the transition state is about 60 kcal/mol and the decomposition energy into radicals about 35 kcal/mol, suggesting that the reaction pathway via the homolytic cleavage to radical species is energetically favorable. Since even the homolytic cleavage requires large energies, the rearrangement reaction is unlikely without the aid of catalysts.

Glutathione was converted by $HNO_2$ into a S-nitrosothiol which was stable in solution and atypically so even as a solid. FAB/MS and IR data have been obtained for the confirmation of structure of S-nitrosogulathione in the crystalline state.

아세토니트릴용액중의 티안트렌 양이온 라디칼 과염소산 염(1)은 Cumene hydroperoxide(4), p-chlorocumene hydroperoxide(2), p-nitrocumene hydroperoxide(3)와 상온에서 반응한다. 이 반응의 공통 생성물로서 티안트렌을 얻었으며 4로 부터 5-(4'-hydroxyphenyl) thianthrenium perchlorate (5), 2로부터 5-(5'-chloro-2'-hydroxyphenyl) thianthrenium perchlorate (7)와 5-acetonylthianthrenium perchlorate (6), 그리고 3으로부터 6만을 얻었다. 이 반응의 양관계는 1의 2몰이 티안트렌 1몰과 티안트렌이움 염(또는 염들) 1몰을 생성한다. 1에 대한 친핵성 활성도는 페놀 > > p-클로로페놀 ${\sim}$아세톤 > > p-니트로페놀 순서임이 밝혀졌다. Hydroperoxide의 산촉매 불균일 분해반응외에도 소량의 균일분해 반응생성물이 3과 4로부터 생성됨을 알았다.
