Abstract

original image

The di-π-methane rearrangement of dibenzobarrelene, described with a two-step mechanism on the triplet state, was pioneered by Howard Zimmerman (1926–2012). In their Communication on page 13097 ff., R. A. Matute and K. N. Houk give a novel mechanistic insight of competing one-step and two-step pathways on the triplet surface. The picture shows a dromedary and a bactrian camel with the transition states on their humps.
