摘要
While investigating RCM of substrates requiring elevated temperatures and extended reaction times, significant isomerization of one of the double bonds in the starting diene was observed with the recently developed [RuIMes] catalyst. This isomerization appeared as an important drawback of the catalyst, but a judicious selection of solvent and additive can completely eliminate this side reaction. (C) 2002 Elsevier Science B.V.
