2,4-Bis(4-methoxyphenyl-1,3,2,4-dithiadiphosphetane-2,4-disulfide, 1, reacts with phenylhydrazones of methylketones to give Δ5-1,2,3-diazaphospholines, 3; in one case 2-methyl-3-phenylindole, 4, was also isolated. Phenylhydrazones of cyclopentanone and cyclohexanone similarly yield the corresponding annulated P-heterocycles, 6a, 6b and as by-products the indoles 7a and 7b, respectively. The sole product
2,4-双(4-

硫化物,1,用甲基酮的苯腙反应,得到Δ 5 -1,2,3- diazaphospholines,3 ;在一个还分离出了2-甲基-3-苯基
吲哚(4),
环戊酮和
环己酮的苯并hydr类似地产生了相应的环化的P-杂环6a,6b,并分别生成了
吲哚7a和7b作为副产物。1与1,3
