A protocol for the hydrocarboxylation of disubstituted alkenes and terminal alkynes providing access to different secondary carboxylicacids and malonic acid derivatives has been developed. This methodology relies on an initial hydroboration using 9-BBN followed by carboxylation with carbondioxide in the presence of a coppercatalyst and the additive, cesium fluoride. Different cyclohexene, styrene
