A New Reaction of α-Chloro-α-chlorosulfenyl Ketones: Facile Syntheses of 3,3-Dichloro- and 3-Chloro-Chroman-4-ones and Thiochroman-4-ones

3-Chloro-3-chlorosulfenylchroman-4-ones are efficiently obtained from chroman-4-ones by treatment with thionyl chloride.Direct oxidation affords 3,3-dichlorochroman-4-ones, whilst conversion to the sulfenamides prior to oxidation provides a facile route to 3-chlorochroman-4-ones.
Triphenylbismuthonio-4,4-dimethyl-2,6-dioxocyclohexane-1-ide and Triphenylbismuthonio-4,4-dimethyl-2,6-dioxo-3,5-dioxan-1-ide. Preparation and Properties of the Stable Bismuthonium Ylides

The title two bismuthonium ylides were obtained in pure form and their reactions with some electrophiles were studied.In contrast with stable ylides of arsenic and antimony, these bismuthonium ylides readily react sith aldehydes and isothiocyanates but th

We have synthesized 1,3-oxathiole-2-thiones from the reaction of zwitterionic iodonium compounds with carbon disulfide.The reaction is shown to be photochemical and possible pathways are discussed.

N,N'-Disubstituted sulfur diimides are reduced by the action of thiophenols to N,N'-disubstituted sulfoxylic diamides R1NHSNHR2.Compounds where R1 = R2 = SO2Ar, COPh enter readily into reaction both with retention and with cleavage of the S-N bond.In reaction with secondary amines and CH acids they are "carriers of sulfur." 2,5-Diaroyl-1,2,5-thiadiazolidine-3,4-diones are formed by the successive action of trimethylchlorosilane and oxalyl chloride on the compounds where R1 = R2 = COPh, COC6H4Cl-p.
REACTIONS OF N,N'-DISUBSTITUTED SULFUR DIIMIDES WITH CH ACIDS. II. REACTION OF N,N'-BIS(PHENYLSULFONYL)SULFUR DIIMIDE WITH 5,5-DIMETHYL-1,3-DIOXOCYCLOHEXANE

The reaction of N,N'-bis(phenylsulfonyl)sulfur diimide with 5,5-dimethyl-1,3-dioxocyclohexane in a ratio of 1:2 leads to the formation of 4-oxo-6,6-dimethyltetrahydro-1,3-benzoxathiole-2-spiro-4',4'-dimethylcyclohexane-2',6'-dione.
