芴硫醚S-氧化物与偶氮烯烃进行(2 + 4)环加成反应,得到2 H -1,2,3-噻二嗪1-氧化物以及少量的区域异构体6 H -1,3,4-噻二嗪1-氧化物。芴硫酮与偶氮烯烃一起经历(2 + 4)区域特异性环加成反应,导致形成6 H -1,3,4-噻二嗪衍生物。二芳基硫酮和二芳基硫酮不能与偶氮烯烃反应。

Benzothiadiphosphole as phosphorus donating reagent for a new route to 2H-1,2,3-diazaphosphole derivatives
Conjugated azoalkenes 2 react at reflux toluene with fused benzothiadiphosphole 1 (or 4) to give the diazaphosphole 3 in 25-52% yields. With this route it is possible to isolate the so far unknown 3a which is difficult to obtain in other reported conditions. The P atom involved in this cycloaddition is the one between the two S atoms.
