Preparation and reactions of N-phenacyl-N-tosylhydroxylamine and -hydrazines was written by Wessig, Pablo;Henning, Hans Georg. And the article was included in Liebigs Annalen der Chemie in 1991.Quality Control of 2-(Bromomethyl)-2-phenyl-1,3-dioxolane This article mentions the following:
O-Alkyl-N-phenacyl-N-tosylhydroxylamines PhCOCH2NTsOCH2R (I; Ts = tosyl; R = H, Ph, p-BrC6H4) were prepared in two steps from O-alkylhydroxylamines. In the presence of a base, I undergo rearrangement and cleavage to N-tosylphenacylamine and aldehydes RCHO. N-Alkyl-N‘-phenacyl-N,N‘-ditosylhydrazines TsNR1NR2Ts (R1 = R2 = CH2COPh or CH2CO2Et; R1 = CH2COPh, R2 = CH2Ph) were obtained by stepwise treatment of N,N‘-ditosylhydrazine with alkyl halides and phenacyl bromide/potassium tert-butoxide/DMF. In the experiment, the researchers used many compounds, for example, 2-(Bromomethyl)-2-phenyl-1,3-dioxolane (cas: 3418-21-1Quality Control of 2-(Bromomethyl)-2-phenyl-1,3-dioxolane).
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. 1,3-Benzodioxole can be synthesized from catechol with disubstituted halomethanes.Quality Control of 2-(Bromomethyl)-2-phenyl-1,3-dioxolane
