A ladder of alternating K2 S2 and K2 O2 rings exists in K[Ph2 P(S)NC(O)Ph]⋅MeOH, the first six-membered "true" heterocycle, in the solid state (see picture). A simple P-N bond-forming reaction between benzamide and Ph2 PCl gives the precursor Ph2 P(S)NHC(O)Ph, from which the potassium salt can be generated by reaction with KOtBu.
固态的第一个六元“真正”杂环K [Ph 2 P(S)NC(O)Ph]⋅MeOH中存在一个交替排列的K 2 S 2和K 2 O 2环的阶梯(参见图片) )。苯甲酰胺和Ph 2 PCl之间的简单PN键形成反应得到前体Ph 2 P(S)NHC(O)Ph,可以通过与KOtBu反应生成钾盐。
