✦ Synopsis

2-tert-Butylanisole and P 4 S 10 react together to give 2,4-bis(3-tbutyl-4-methoxyphenyl) 1,3,2,4-dithiadiphosphetane 2,4-disulfide (LR*) which was characterized by X-ray crystallography. Comparative thionation reactions of LR* and a range of P-S compounds were investigated. It was found that LR*, in many cases, gives better yields of thionated complexes than Lawessons Reagent when the reactions are performed at room temperature.
