✦ Synopsis

Different modes of decomposition of dienic diazoketones have been studied, leading to either formation of vinyl-cyclopropanes or Wolff-rearranged acids or esters. Preparation of four homologous dienic acids is described. Recently we required a series of homologous diazoketones 1 in connection with our investigation of the intramolecular carbenoid addition to 1,3-dienes' to produce N2 * A procedure for protection of &-unsaturated acid chlorides is available; N.R. Rosenquist, O.L. Chapman, J. Org. Chem., 9, 3326 (1976).
