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
