In the formation reaction of spiropentanes by the reaction of sulfonium cyclopropylides with carbonyl compounds, a mechanism involving an oxathietane was proposed as an alternative one involving a ring expansion to a σ-sulfurane having an oxirane ring followed by reductive elimination of the sulfide, see

Products 5, 10, 12, and 13 are thought to be formed via a mechanism similar to that reported in ref 2b. Benzaldehyde (11) and 14 seem to be formed as follows: the oxosulfonium ylide, which is formed by retroaddition of 3 together with 5, reacts with 13 to give 14 and the corresponding inner oxosulfonium oxide, which undergoes C-S bond cleavage to afford 11 and 12.
