The decyanation of secondary aliphatic nitriles and the 2-fold decyanation of malononitriles leading to alkanes in the presence of 1,3-dimethylimidazol-2-ylidene borane (diMeImd-BH3) are reported. These reactions proceed via a radical mechanism that involves the addition of a borane radical to the nitrile to form an iminyl radical, followed by cleavage of a carbon-carbon bond. Theoretical calculations suggest that the β-cleavage of these iminyl radicals, which affords NHC-BH2CN and the corresponding alkyl radicals, is the rate-determining step in this reaction.

The procedure was proposed for the synthesis of various dipyridyldiamides. Their various properties in the series of rare-earth elements were studied. The possibility to use the synthe-sized compounds in polymer membranes of electrochemical sensors for th

We report five o-phenylenediamines which are substituted by an aliphatic chain containing n carbon atoms (n = 4, 6, 8, 10, 12).We describe a well adapted general synthetic method using Schmidt's reaction.The diamines were then transformed into 2-benzimidazolemethanethiols and their related S-methyl derivatives which structures were checked by (1)H NMR.
Study of the Influence of Molecular Length on the Characteristics of the Ordered Smectic Phase.

Study of DTA and X-rays of p-phenyl-benzylidene-p'-alkylanilines of mesomorphic phases demonstrates the predominant role of the aliphatic chain length. In effect, it governs the appearance of the different phases; the correlation between layers decreases for greater chain lengths. The nonlinear variations of SmB layer thickness for these compounds shows clearly the importance of steric effects coupled with the molecular length with respect to the dipolar effect.
