We report the efficient carboxylation of bromides and triflates with K2CO3 as the source of CO2 in the presence of an organic photocatalyst in combination with a nickel complex under visible light irradiation at room temperature. The reaction is compatible with a variety of functional groups and has been successfully applied to the synthesis and derivatization of biologically active molecules. In particular, the carboxylation of unactivated cyclic alkyl bromides proceeded well with our protocol, thus extending the scope of this transformation. Spectroscopic and spectroelectrochemical investigations indicated the generation of a Ni0 species as a catalytic reactive intermediate.

-
Paragraph 0062-0071, (2015/07/15)
Process for preparing isononanoic acid proceeding from 2-ethylhexanol, characterized in that (a) 2-ethylhexanol is dehydrated to octene in the presence of a catalyst; (b) the octene obtained in step a) is reacted in the presence of a transition metal compound of group VIII of the periodic table of the elements with carbon monoxide and hydrogen to give isononanal; and (c) the isononanal obtained in step b) is oxidized to isononanoic acid.
