Abstract
The present invention concerns a new efficient method for the selective transformation, under mild conditions and in aqueous medium, of gaseous (ethane, propane and n-butane) and liquid (n-pentane, n-hexane, cyclopentane and cyclohexane) alkanes into carboxylic acids bearing one more carbon atom, characterized by a single-pot low-temperature (25-60° C.) reaction of the alkane with carbon monoxide in water/acetonitrile liquid medium, either in the absence or in the presence of a metal catalyst, in systems containing also an oxidant (a peroxodisulphate salt).
