Syntheses and Thermal Reactions of Cyclic Sulphenium Ylides: 2-Alkyl(or aryl)-1-benzoyl-1H-thianaphthalen-2-ium-1-ides and 2-Alkyl(or aryl)-1-benzoyl-3,4-dihydro-1H-2-thianaphthalen-2-ium-1-ides

Pummerer cyclization of phenacyl phenethyl sulphoxide (5) was carried out using trifluoroacetic anhydride to give 1-benzoyl-3,4-dihydro-1H-2-thianaphthalene (6) in a good yield.Alkylation (or arylation) of 1-benzoyl-1H-2-thianaphthalene (1) and the 3,4-di

SYNTHESIS AND THERMAL REACTIONS OF 2-ALKYL(OR ARYL)-1-BENZOYL-3,4-DIHYDRO-2-THIANAPHTHALENES

1-Benzoyl-2-methyl-3,4-dihydro-2-thianaphthalene (4a) underwent novel intermolecular 1,4-rearrangement in refluxing toluene to give an enol ether 5a, while rearrangement of 2-phenyl derivative 4e proceeded intramolecularly in refluxing xylene to afford a 1,4-rearranged enol ether 5b.On the other hand, ylides 4a-e were refluxed in alcohols to afford some ring-opened products 10-12.
