temperature resulted in the formation of 3,3-di-tert-butylthiirane-2-thione (4 a) in high yield. The oxidation of 4 a with mCPBA (mCPBA=m-chloroperbenzioc acid) gave 3,3-di-tert-butylthiirane-2-thione S-oxide (6) almost quantitatively. The reactions of 4 a with dimethyl acetylenedicarboxylate (DMAD) and benzyne afforded dimethyl 2-(2,2,4,4-tetramethylpentan-3-ylidene)-1,3-dithiole-4,5-dicarboxylate (13)
在室温下用Lawesson试剂处理二叔丁基硫代乙烯酮S-氧化物(5a)导致以高收率形成3,3-二叔丁基噻吩烷-2-硫酮(4a)。用mCPBA(mCPBA =间氯过苯二酸)氧化4 a几乎定量得到3,3-二叔丁基噻吩烷-2-硫酮S-氧化物(6)。4a与乙炔基二羧酸二甲酯(DMAD)和苯并炔的反应得到2-(2,2,4,4-四甲基戊基-3-亚烷基)-1,3-二硫代-4,5-二羧酸二甲酯(13)和2- (2,2,4,4-四甲基戊基-3-亚烷基)苯并[d] [1,3]二硫醇(15)的收率很高,这表明4 a是极好的1,3-偶极子。4a与亚乙基双(三苯基膦)铂(16)的反应以高收率得到二硫代巯基-铂络合物(22)。通过X射线晶体学分析确定22的结构。
