2-dithiaphospholanes 12a–c are formed as minor byproducts of the thermal isomerization of phosphiranes 10. Compound 10a slowly rearranges in solution to give 12a as the sole product. Compounds 12 may result from a formal [3+2] cycloaddition reaction of an α,β-unsaturated thione, formed by partial decomposition of 10, with a dipolar valence isomer of 10 or 11, featuring aW(CO)5-complexed thiocarbonyl-phospha-ylide dipole
