Methyl-halogenated Allyl Methyl Sulfoxides and Sulfones and the Synthesis of Halogenated Sulfines

Allyl methyl sulfoxides R1R2R3C-S(O)-CH2CH=CH2 1a-7a (R1, R2, R3 = H, F, Cl, CF3) as well as the corresponding sulfones 1b-7b were synthesized.The sulfoxides substituted at the methyl group are in equilibrium with the allyl sulfenates R1R2R3-S-OCH2CH=CH2 depending on temperature and kind of substitution.By pyrolysis of the sulfoxides 2a, 3a, 4a, and 7a the sulfines Cl2C=SO and (CF3)2C=SO could be prepared, and evidence for the existence of the sulfines ClFC=SO and F2C=SO could be obtained.The new pentenes 12 and 14 are described.

The corresponding S-oxides 2-6 could be obtained by oxidation of 2,2,4,4-tetrakis(trifluoromethyl)-1,3-dithietane (1).Similar oxidation of 2,2,4,4-tetrakis(trifluoromethyl)thiirane (8) yields the episulfoxide 12, but not the episulfone 14.Pyrolysis of 2, 3, 5, and 6 have been investigated and bis(trifluoromethyl)sulfine (7) could be isolated as the first member of perfluoroalkylsulfines as well as the sulfonylfluoride 13 being the product of isomerization of bis(trifluoromethyl)sulfene (9). 7 could also be obtained by ring opening from 3 with bases and by oxidation of hexafluorothioacetone (11), respectively.Solvolytic ring opening in 5 and 6 yields the sulfones 16 and 17.
