Abstract

Kinetics of cycloaddition of tropone to 6‐methylfulvene and 6,6‐dimethylfulvene were determined. It was concluded that steric effects play a role in [6+4] cycloadditions.

## Abstract 2‐Chlorotropone reacts with 6,6‐dimethylfulvene to form a 1:1 adduct only. From kinetic data as well as from structural evidence the conclusion was drawn that the [6+4] cycloidditions between tropones and cyclopentadiene or fulvenes are highly disfavoured by substituents at the reaction
