title: Cross and ring-closing metathesis of 1,3-diynes: metallotropic [1,3]-shift of ruthenium carbenes.
abstract: The regio- and stereoselective enyne CM and RCM reactions involving 1,3-diynes have been developed. The ring-closing metathesis of enediynes induces a facile metallotropic [1,3]-shift of alkynyl ruthenium carbene species, thereby providing a unique entry into the synthesis of fully conjugated 1,5-diene-3-ynes.
