Cyclohexanone and cyclopentanone react with 2,4 - bis - 4 - methoxyphenyl) - 1,3,2,4 - dithiadiphosphetane 2,4-disulfide (lawesson Reagent (LR) at 80° with formation of new spiro - 1,3,5,2 - trithiaphosphorines 1 and 2, respectively. 2-Methyl and 2-phenylcyclohexanone also react with LR at 80° producing the enethiols 3 and 4, which on storage are transformed into the sulfides 5 and 6. Unsaturated cyclohexanones
环己酮和环戊酮与2,4-双-4-甲氧基苯基)-1,3,2,4-二硫代二膦2,4-二硫(劳森试剂(LR))在80°反应形成新的螺-1,3,5 ,2--三硫代磷酸1和2. 2-甲基和2-苯基环己酮也与LR在80°下反应生成烯硫醇3和4,在储存时转化为硫化物5和6,不饱和环己酮7-9被转化。与LR在60°下反应几个小时后,生成10-12的相应硫代酮。2-羟基酮与形成1,3,2-氧杂磷腈和类似地2-氨基酮的LR得到1,3,2-噻唑磷。芳族酮与LR反应生成相应的硫代酮。X射线分析证实,噻吩芴酮二聚形成环状二硫化物31。
