Isobutene can be Koch carbonylated to trimethylacetic acid.The reaction proceeds via protonation of the alkene leading to a carbenium ion. Several acids can be used including HF, sulfuric, phosphoric. These can be used alone or in combination with Olah type super acids.With longer reaction times, all butene isomers will rearrange to trimethylacetic acid.
