The reaction of carboxylicacidchlorides (1) with chloromethyl-lithium generated in situ(1 : 2 molar ratio) in the presence of lithium iodide leads, after hydrolysis, to the corresponding homologated 2-substitutedallylalcohols (2).
A novel reaction involving allene and water took place using palladium(0)–triphenylphosphine as a catalyst in the presence of carbondioxide to yield 3-methyl-2-methylene-3-buten-1-ol, selectively. A related reaction of allene with methanol or ethanol was found to occur without carbondioxide.
