Gas-Phase Conversion of 1,3-Dithiolane-2-Thione Into 1,3-Dithiolan-2-One Over Molybdenum Trioxide

Abstract: Gas-phase reaction of 1,3-dithiolane-2-thione over molybdenum trioxide supported on pumice stone results in efficient conversion into 1,3-dithiolan-2-one. The solid reagent is regenerated on exposure to air and thus acts as a catalyst for the overall conversion of the thione and oxygen from the air into the ketone and sulfur dioxide. The process can be carried out under either dynamic vacuum or atmospheric pressure flow conditions and using a solid reagent prepared either by physical mixing of MoO … Show more

“…More recently, FVP over molybdenum trioxide has been used in conversion of 1,3-dithiolane-2-thione into 1,3-dioxolan-2-one. 43 The FVP technique has been applied to effectively solve various other problems. It provided the ideal method for generation of the highly reactive and unstable 1,4-oxazine 46 by elimination of CO2 and isobutene from the Boc precursor 45, allowing spectroscopic characterisation of this fundamental heterocycle for the first time.…”
