Aqueous suspensions of Ru(0) nanoparticles, stabilized with hydroxyethylammonium salts and possessing sizes around 2 nm, proved to be active and selective in the mild oxidation of α-pinene in the presence of tert-butylhydroperoxide, in neat water. Verbenone, a product of great interest for fine chemistry, was obtained as major product with yield up to 41% under optimized conditions. 2-hydroxy-3-pinanone was identified as a co-product of the reaction, but with very low amount (7%). Kinetic investigations allowed determining the potential reaction intermediates and by-products. Moreover, mechanistic studies with radical scavengers confirmed that α-pinene oxidation mainly implies both carbon- and oxygen-centered radicals.

EDA-iodine complex with trialkylamine oxides in dichloromethane have been investigated spectrophotometrically.Thermodynamic (KADc,-ΔG0) and spectral (ΕADλ) characteristics of these complexes were determined.The absorption band of iodine in the visible region was blue-shifted with a variable maximum, depending on the structure of the amine oxide.The KADc and ΕADλ values were calculated using a modified method.A non-linear relationship KADc=(R), where R is the number of carbon atoms in the alkyl chain, was found.
