Sulfur Heterocycles

An efficient approach has been developed for the synthesis of new phosphorus–sulfur heterocycles by a one-pot three-component condensation reaction of a four-membered-ring thionation reagent [Lawesson’s reagent or its ferrocene analogue (2,4-diferrocenyl-1,3,2,4-diathiadiphosphetane 2,4-disulfide)], an alkane- or arenedithiol, and a dihaloalkane at room temperature in the presence of triethylamine. The simple synthesis method with mild conditions (room temperature and normal reactant concentrations) enhances further the application of the multicomponent reaction in the preparation of novel phosphorus–sulfur heterocycles. Six representative X-ray structures confirmed the formation of these macrocycles.
