Barium-catalyzed direct Mannich-type reactions of a β,γ- unsaturated ester are described. The Ba-catalyst not only promoted the Mannich-type reactions, but also isomerized Mannich adducts to afford β-methyl aza-Morita - Baylis - Hillman-type products in 6

A concise and elegant protocol was developed to prepare linear amines by regioselective hydroaminomethylation of terminal olefins with pyrrole-based tetraphosphorus ligands. It has been documented that the reactivity of the ligand is modulated by the substituent of the biphenylphosphane moiety. Ligand L5 containing electron-donating groups exhibited the highest reactivity, with up to 70.9 n/i ratio and 99.5% amine selectivity for 1-pentene and a 31.3 n/i ratio and 97.9% amine selectivity for 1-hexene.

KINETICS OF OXIDATIVE COUPLING OF PHENOLS. OXIDATION OF RESORCINOLS BY ALKALINE HEXACYANOFERRATE (III)

, p. 1099 - 1105 (2007/10/02)
The reactions of resorcinol and 5-methylresorcinol (orcinol) with alkaline hexacyanoferrate(III), at constant ionic strength, gave coupled products.The rate of the reaction was dependent on the first power of concentration of each substrate, oxidant and alkali.The reaction pathway could be mechanistically visualized as proceeding via a radical intermediate formed in the rate determining step.This radical intermediate was detected by ESR spectroscopy, and showed an absorption in the visible region, and a typical absorption band at 1560 cm-1 in its infrared spectrum.

The reactions of resorcinol and 5-methylresorcinol(orcinol) with alkaline hexacyanoferrate(III), at constant ionic strength, gave coupled products.The rate of the reaction was dependent on the first powers of the concentrations of each component - substrate,oxidant and alkali.The reaction pathway was via the formation of a radical intermediate, which was detected by esr spectroscopy, and showed an absorption at 650 nm in the visible region, and a typical absorption band at 1560 cm-1 in the infrared spectrum.
