Abstract

Abstract: The kinetics of the I*-catalyzed isomerization of the retinal isomers were studied. The all-trans isomer formed 13-cis-retinal rapidly with a rate constant of 1.9 X s-]. The reverse reaction occurred with a rate constant of 4.5 X IO4 sI. The 11-cis isomer was first converted to all-trans-retinal with a rate constant of 3.1 X lo4 8, although the 13-cis isomer was also rapidly formed. The 9-cis isomer was isomerized to the 9-cis, l3-cis isomer before ...
