Phosphorus–sulfur–nitrogen heterocycles from diferrocenyl dithiadiphosphetane disulfide

Ni(II) complexes with 1,3,2,4‐dithiadiphosphetane 2,4‐disulfide‐based ligands: Structural insights, theoretical studies, and anticancer activities

“…Over the past few decades, the compounds bearing a P 2 S 2 moiety are dubbed 2,4‐diorganyl‐1,3,2,4‐dithiadiphosphetane‐2,4‐disulfide (DTPS, (RP(S)S) 2 ) have attracted much attention, because they serve as the starting material of a series of new organodithiophosphorus compounds. [ 1–7 ] The prototype of the DTPSs is the so‐called Lawesson reagent. [ 8 ] Other analogs, for example, Belleau reagent, [ 9 ] Yokoyama reagent, [ 10 ] and Davy reagent [ 11 ] have been reported afterward (Figure 1).…”
