Stannylfuranones 1 and 2 were prepared by ipso radical desulfurative stannylation of phenylsulfanylfuranones 3 and 16. Compounds 1 and 2 underwent Stille coupling reactions with aryl iodides to give 3- and 4-arylfuran-2(5H)-ones.

3- and 4-trialkylstannylfuranones (2) and (3) have been prepared by an interesting desulphurative stannylation reaction; 3- and 4-substituted 2-(5H)-Furanones (12) and (13) may be prepared via palladium-catalysed cross coupling of (2) and (3) with aryl iodides

Bistributylstannyl-2(5H)-furanone 4a has been prepared from 3-(tetrahydropyran-2-yl)oxy but-2-ynoate and shown to exhibit good selectivity in its Stille reactions with a range of halogenated compounds, leading to 4-substituted-3-stannyl-2(5H)-furanones, in generally moderate yield. Under certain reaction conditions, doubly substituted products were also isolated from the reactions. The 3,4-bistrimethylstannyl
