Benzoylphenyl-1-methylpyrazoles. Synthesis, characterization, and spectra was written by Kano, Kunio;Scarpetti, David;Warner, John C.;Anselme, Jean Pierre;Springer, James P.;Arison, Byron H.. And the article was included in Canadian Journal of Chemistry in 1986.Application of 3418-21-1 This article mentions the following:

The synthesis and characterization of all 6 isomers of benzoylphenyl-1-methylpyrazole (I) (R = Ph, R¹ = PhCO) are described. Thus, PhCOCH:CH₂ was treated with PhCHN₂ in Et₂O to give 60% benzoylphenylpyrazoline II (R² = H) which was treated with NaH and then MeI in Me₂SO to give II (R² = Me). Heating the latter II with S gave 69% the pyrazole III. The x-ray crystal structure of I (R = 4-Ph, R¹ = 3-PhCO) is also reported. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)-2-phenyl-1,3-dioxolane (cas: 3418-21-1Application of 3418-21-1).

2-(Bromomethyl)-2-phenyl-1,3-dioxolane (cas: 3418-21-1) belongs to dioxole derivatives. Dioxoles, particularly fluorinated dioxoles, are used as co-monomers to make polymers that find use in forming protective coatings for chemical resistance. Although benzodioxole is not particularly important, many related compounds containing the methylenedioxyphenyl group are bioactive, and thus are found in pesticides and pharmaceuticals.Application of 3418-21-1

And the article was included in Journal of Organic Chemistry in 1989.COA of Formula: C7H13ClO2 This article mentions the following:

A general synthetic route to α-methylene β-lactams involves the regioselective electrophilic substitution of the dianion generated from PhSO₂CH₂C(:CH₂)CONHPh (I). A convergent synthesis of conocandin N-phenylamide [(3R^*,4R^*)-II was carried out. Key steps in the synthesis are the stereoselective introduction of the C(9)-C(10) trisubstituted double bond of the amide using the dianion of I and the transformation of the sulfonyl group in the intermediate amide, (E)-9-hydroxy-10-methyl-2-methylene-N-phenyl-3-(phenylsulfonyl)-9-hexadecenamide, prepared from (E)-7-methyl-6-tridecenal and the dianion of I, into a hydroxy function via [2,3]-sigmatropic rearrangement of the selenoxide. In the experiment, the researchers used many compounds, for example, 2-(4-Chlorobutyl)-1,3-dioxolane (cas: 118336-86-0COA of Formula: C7H13ClO2).

Lithiation reactions catalyzed by linear and cross-linked arene-based polymers. Generation of functionalized organolithium compounds was written by Candela, P.;Gomez, C.;Yus, M.. And the article was included in Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii) in 2004.Computed Properties of C7H13ClO2 This article mentions the following:

Lithiation of various substrates, such as chlorinated acetals (e.g. 2-(4-chlorobutyl)-1,3-dioxolane), α-chloro ether, dichloro derivatives, benzo-fused heterocycles (e.g. isobenzofuran), and allyl and benzyl derivatives, with excess Li powder in the presence of a catalytic amount of soluble linear or insoluble cross-linked arene (naphthalene or biphenyl)-based polyolefins, yields the expected organolithium intermediates. The latter react with electrophiles (e.g. Et₂CO) either in two steps or under Barbier-type reaction conditions to afford the corresponding adducts. The catalyst is easily recuperated by filtration at the end of the process, and the procedure can be regarded as a reasonable alternative to the use of free arenes as electron carrier in lithiation reactions.
