the deuterated sulfone, la in 107, CD30D-CD3CN. The methyl group of phenyl methyl sulfone was only derived from the methylene carbon between the two sulfonyl groups. Moreover, nmr analysis of the photolysis mixture without removal of solvent indi- cated a yield of 1,2-diphenylethane greater than 907,.

suppliers and used without further purification. Benzyl trifluoromethyl sulfone 3a1, benzyl phenyl sulfone 1a2, benzyl 2-pyridyl sulfone 1c, and benzyl 4-nitrophenyl sulfone 1e3 were prepared according to procedures reported in the literature. 1-Bromo-4-(methoxymethoxy)benzene 7d4,
observation that benzyl phenyl sulﬁde is oxidized to the corresponding sulfone indicates that the reaction pro-ceeds by way of an oxygen transfer mechanism. If the reaction involved electron transfer instead of oxygen transfer, substantial amounts of benzaldehyde would have been formed.16,17 Most other solvent free oxida-Scheme 3.
Diphenyl sulfone is an organosulfur compound with the formula (C 6 H 5) 2 SO 2.It is a white solid that is soluble in organic solvents.It is used as a high temperature solvent. Such high temperature solvents are useful for processing highly rigid polymers, e.g., PEEK, which only dissolve in very hot solve

In their recent OBC publication, Prof Cathleen M. Crudden et.al. of Queen's University, Ontario developed a beautiful protocol for the transition metal-free desulfonative borylation of benzyl sulfones using simple pyridine derivatives as catalysts (scheme 2). They reported the borylation of cyclic sulfones to afford functionalized sulfones ...

A sulfone is a chemical compound containing a sulfonyl functional group attached to two carbon atoms. The central hexavalent sulfur atom is double-bonded to each of two oxygen atoms and has a single bond to each of two carbon atoms, usually in two separate hydrocarbon substituents.
Benzyl sulfone is a cyclic sulfone. Benzyl sulfone (Dibenzyl sulfone) on pyrolysis at 290°C yields stillbene and toluene. Mechanism of pyrolysis of dibenzyl sulfones at 600-700°C has been reported. Benzyl sulfone forms sodium salt with metallic sodium and with sodium ethoxide. Cryoscopic behavior of benzyl sulfone was investigated. Packaging
Using diethyl sulfone with α-tetralone lead to pure naphthalene. Condensation of isobutyraldehyde and dimethyl sulfone using potassium t-butoxide gave isoprene in low yield. Using benzaldehyde and benzyl phenyl sulfone in N,N-dimethylacetamide gave 1,2-diphenyl-1-phenylsulfonylethylene, N,N-dimethylcinnamide, and a complex condensation product.

R' = H, was similarly prepared from benzyl phenyl sulfone (6, R = Ph) in 60% yield. Replacement of epibronlohydrin by 4-bromo-I,2-epoxybutane in the above sequence lead to the formation of 3-phenyl- sulfonylcyclopentano1 and 3-phenyl-3-phenylsul- fonylcyclopentanoi in 35 and 75% yield, respectively.
In IUPAC nomenclature the prefix benzyl refers to a C 6 H 5 CH 2 substituent, for example benzyl chloride or benzyl benzoate. Benzyl is not to be confused with phenyl with the formula C 6 H 5. The term benzylic is used to describe the position of the first carbon bonded to a benzene or other aromatic ring.
Functional studies of PTP can be greatly facilitated by small molecule probes that covalently label the active site of a PTP through an activity-dependent chemical reaction. In this communication, we characterize phenyl vinyl sulfonate (PVSN) and phenyl vinyl sulfone (PVS) as a new class of mechanism-based PTP probes.

Benzyl phenyl sulfone2 (3a) (Scheme 1). The general procedure was followed with benzyl methyl carbonate (1a) (167 mg, 1.00 mmol) and sodium benzenesulfinate (2a) (181 mg, 1.10 mmol). The crude product was purified by a flash column chromatography (EtOAc/hexane = 1/1) to give 3a (221 mg, 95%) as colorless solid: 1H NMR (400 MHz, CDCl

In sharp coatrast, however, to the reaction with the lithium reagent, the reaotion of phenyl benzylsulfonate with phenylmagnesium bromide under comparable conditions gave only benzyl phenyl sulfone (III) in a high yield. in addition to a corresponding yield of phenol. In this case neither I nor II was obtained.
The hydrocarbyl groups (R) can be identical or different, such as dimethyl sulfone (CH3 • SO2 • CH3), ethyl phenyl sulphone (C6H5 • SO2 • C2H5), diethyl sulfone, diphenyl sulfone, sulfolane, bisphenol S, etc. The sulfur in sulfones is of high valence; and sulfone is a stable crystalline organic compound which can't be reduced into R2S.
