It inhibits the development and induces regression of premalignant adenomatous polyps. Lipoxygenase and Cox-2 inhibitor. It has a role as a cyclooxygenase 2 inhibitor, an EC 126.96.36.199 (arachidonate 5-lipoxygenase) inhibitor and an apoptosis inducer. It is a sulfone, a monocarboxylic acid and an organofluorine compound. It derives from a sulindac.
Phenyl or benzyl? Phenyl and benzyl are not the same and can not be used interchangeably. Take care not to confuse terminology : benzyl substituent = C 6 H 5 CH 2 phenyl substituent = C 6 H 5; Here are some examples:

Benzhydryl Phenyl Sulfone was obtained by heating a mixture of sodium benzenesulfinate (0.21 g, 1.3 mmol) and benzhydryl chloride (0.26 g, 1.3 mmol) in DMSO at 70 °C. After completion of the reaction (4 h), the reaction mixture was cooled to room temperature, diluted with water, and extracted with ethyl acetate.

A palladium complex generated in situ from [Pd(η 3-C 3 H 5)Cl] 2 and DPEphos [bis(2-diphenylphosphinophenyl)ether] catalyzed the nucleophilic substitution of benzylic carbonates with sodium arenesulfinates in DMSO at 80°C. The reaction gave a variety of benzylic sulfones in high yields.
3,5-Bis(trifluoromethyl)phenyl (BTFP) sulfones 7 have been employed in the Julia−Kocienski olefination reaction with carbonyl compounds. Sulfones 7 are readily prepared in high yields (64−97%) from commercially available 3,5-bis(trifluoromethyl)thiophenol through an alkylation/oxidation two-step sequence.
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. For example, (C 6 H 5)(CH 3) 2 C + is referred to as a "benzylic" carbocation. The benzyl free radical has the formula C 6 H 5 CH • 2.
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
Literature References. Active methylene compound: the lithio-derivative reacts with carbonyl compounds to give vinyl sulfones which can be reductively cleaved, e.g. with Al amalgam, to alkenes, in a reaction analogous to the Julia olefination (see Ethyl phenyl sulfone, A10710): J. Chem. Soc., Chem. Commun., 351 (1973).

In organic chemistry, the phenyl group or phenyl ring is a cyclic group of atoms with the formula C 6 H 5.Phenyl groups are closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a functional group.
