The allyl anions generated from 4H-dinaphtho[2,1-f:1′,2′-h][1,5]dithionin (6) and 2-ethenyl-dinaphtho[2,1-d:1′,2′-f][1, (8) rearranged both to the thiolate 10 which further reacted with water or methyl iodide to afford 9 or 12 respectively. A similar behavior was exhibited by the anion of 4H-dibenzo[f,h][1,5]dithionin (15).
由4 H -dinaphtho [2,1- f:1',2'- h ] [1,5] dithionin(6)和2-乙烯基-dinaphtho [2,1- d:1',2生成的烯丙基阴离子′ -f ] [1,(8)均重排为硫醇盐10,其进一步与水或甲基碘反应,分别得到9或12。4 H-二苯并[ f,h ] [1,5]二硫精的阴离子表现出相似的行为(15)。
