Promoted by samarium metal in DMF, aroyl chlorides react readily with iso-pentylene in a four-molecule manner, which offers an efficient stereo- and regiospecific synthesis of (E)-β,γ-unsaturated carbonyl compounds and also provides a facile method for the construction of monoterpene skeleton. The reaction is an additional example of organic reactionsmediated by direct use of unactivated metallic
Photoaccelerated Reductive Coupling of Acid Chlorides with Conjugate Dienes and Styrenes by Use of Neodymium Metal in<i>N</i>,<i>N</i>-Dimethylacetamide
Upon photoirradiation, neodymium metal powder in N,N-dimethylacetamide (DMAC) exhibits excellent reducing ability for the reductive coupling of benzoyl chlorides with conjugate dienes and styrenes.
