Clean and efficient microwave-solvent-free synthesis of 1-(2′,4′-dichlorophenacyl) azoles

Microwave induced N-alkylation of several azoles with 2,2′,4′-trichloroacetophenone (TCA) under solvent-free conditions allowed to obtain the corresponding 1-(2′,4′-dichlorophenacyl) azoles with satisfactory to good selectivities and yields. TGA and DSC measurements were achieved for the synthesized compounds and showed a close relationship between the thermal behavior and the reaction temperature under microwave heating. Non-purely thermal microwave effects were evidenced during the alkylation of pyrazole and 1H-indazole under the selected conditions.

Synthesis and 13C NMR Spectra of cis- and trans-methyl>>-1,3-dioxolane-4-methanols

Syntheses and 13C nmr spectra of a number of cis and trans 2-(haloaryl)-2--4-(hydroxymethyl)-1,3-dioxolanes are described.The haloaryl groups are 2,4-dichloro, 2,4-difluoro-, 4-chloro- and 4-bromophenyl.In these series, some of the cis compounds become available through crystalline bromo benzoates 5.Separations of some trans isomers are achieved through fractional crystallizations of imidazolyl benzoate nitrates 6.Stereochemical assignments are based primarily on one major 13C chemical shift difference, namely that of C-4 of the 1,3-dioxolane ring, the chemical shift of the trans isomers being 1.0-2.5 ppm downfield from that of the cis isomers.
