Stereochemistry of the [4 + 2] cycloadditions of trans,trans- and cis,trans-2,4-hexadiene to C60
(2002)The [4 + 2] cycloaddition of trans,trans-2,4-hexadiene with C60 proceeds via a concerted mechanism with retention of stereochemistry in the cycloadduct 1a. However, when cis,trans-2,4-hexadiene reacts with C60, isomerization ...
