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

The applications of a new supported tribromide reagent based on poly(vinylbenzyltrimethylammonium tribromide) resin (Amberlite 717) were reported. This supported tribromide resin was used directly in α-bromination and α-bromoacetalization of acetophenones without any other catalyst under mild conditions.
