The carbonylation at the benzyl C-Hal bonds (Hal = F, Cl) of a number of polyfluorinated alkylbenzenes and benzocycloalkenes using carbon monoxide in the presence of SbF is described. The reaction provided the corresponding -arylcarboxylic acids or their methyl esters following aqueous or methanol treatment. The products of double carbonylation were obtained from bis(chloromethyl)tetrafluorobenzenes and benzal fluorides.

Article Synopsis
  • The first study in Russia used mitochondrial DNA (D-loop) to investigate the genetic structure of brown rats (Rattus norvegicus) across European and Asian regions.
  • Three distinct clades of brown rats were identified: one in European Russia and two in Asian Russia.
  • The domestic subspecies (R. n. norvegicus) showed separate European and Asian lineages, while the wild subspecies (R. n. caraco) from the Russian Far East represented a unique genetic lineage.

Article Synopsis
  • A new method has been created for synthesizing both symmetric and asymmetric fused spiro[4.4]-nonane-dione derivatives.
  • It involves a Diels-Alder reaction using spiro[4.4]nona-2,7-diene-1,6-dione as the dienophile, and the adduct undergoes immediate aromatization.
  • Various systems, such as tetrabromoxylene/NaI, 1,3-diphenylisobenzofuran/BF, or substituted cyclones, can generate an active diene component for the reaction.

The biologically active compound 3-aminopropylsilatrane (a compound with a pentacoordinated silicon atom) underwent an aza-Michael reaction with various acrylates and other Michael acceptors. Depending on the molar ratio, the reaction yielded Michael mono- or diadducts (11 examples) containing functional groups (silatranyl, carbonyl, nitrile, amino, etc.).
