1,2-Dithiolylium-4-olates combine with 1,3-dienes to produce new 7,8-dithiabicyclo[4.2.l]non-3-en-9-one derivatives as a result of a 1,3-dipolar [4 + 3] cycloadditionreaction, whereas the reaction of 3,5-bis(methylthio)-1,2-dithiolylium-4-olate with 2,3-dimethylbuta-1,3-diene affords two isomeric 1:2 adducts.
