  A new robust methodology for gram-scale iron-catalyzed cross-coupling between alkyl Grignard reagents and alkenyl or aryl halides is developed. This method does not require toxic additives such as NMP or expensive ligands. Its efficiency relies on the use of simple alkoxide magnesium salts as additives. On the basis of these results, a new procedure for one-pot synthesis of substituted benzamides from

• Unique variations of the distribution coefficients of homologues in the perfluorodecalin-acetonitrile heterophase system

  The properties of the heterophase system perfluorodecalin-acetonitrile differ significantly from those of other combinations of the organic solvents limitedly soluble in each other. While for the most of such combinations the distribution coefficients (K (d)) of homologues increase in going from the simplest to next members of the series, in the case of perfluorodecalin-acetonitrile they remain almost constant. This provides a possibility to use the values of K (d) directly for the group identification of analytes, and first of all allows distinguishing isomeric alkenes and cycloalkanes, as well as the isomers of the hydrocarbons with greater formal unsaturation.
