The thermally-induced prototropic isomerization of η4-1,3-, η4-1,4-, η4-1,5-dialkenes complexed to (η5-cyclopentadienyl)cobalt
摘要:
This study reports a series of facile, thermally-induced, prototropic isomerizations of eta4-1,4- and eta4-1,5-dienes of (eta5-cyclopentadienyl)cobalt to their corresponding eta4-1,3-complexes. The data indicate the E-isomers to be thermodynamically favored over the Z-isomers. Furthermore, in the case of eta4-hexadiene complexes, the eta4-2,4-EE-isomer is observed to be thermodynamically preferred relative to either the eta4-2,4-E,Z- or eta4-1,3-E-isomers.
