The ratio of exo ‐/ endo ‐adducts formed in the reaction of acrylic acid derivatives (1) with cyclopentadiene is hardly influenceable in the homogeneous phase; in contrast, in the heterogeneous phase it strongly depends on the carrier material. For example, when acrylonitrile reacts with cyclopentadiene in a homogeneous phase to give the products in the ratio 3:1, the same reaction on Al 2 O 3 leads to a ratio of almost 1:1.
