A compound related to Lawesson’s reagent named NpP2S4 has been formed by the reaction of 1-bromonaphthalene with P4S10 this is a 1324-dithiadiphosphetane 24-disulfide which has a naphth-18-diyl group holding the two phosphorus atoms together. The mechanism by which the NpP2S4 forms is unclear but it is thought to occur through some free radical process and naphthalene has been detected as a side product in its synthesis.
