Hopf published the only previous comprehensive review on branched oligoenes that had the title “Dendralenes: A Neglected Family of Hydrocarbons”. The dendralenes are no longer neglected. Research into the synthesis, properties, and applications of dendralenes is rapidl...

The cycloaddition reaction of a tetraaryl[5]cumulene with the electron‐deficient olefin tetracyanoethylene affords unusual products, including functionalized dendralenes and alkylidene cyclobutanes, as well as a symmetric [4]radialene that shows unique solvatochromism,...

Sherburn 来源：[J].Pure and Applied Chemistry(IF 3.386), 2013, Vol.85 (6), pp.1227-1239De Gruyter 摘要：We present herein an overview of our ongoing studies with dendralenes. The first synthetic routes to this fundamental family of compounds have revealed long-hidden secrets in hydrocarbon chemistry and set the scene for synthetic and materials chemistry applications.

The dendralenes adopt two different conformers in solution and solid state and the transformation between the structures can be controlled by light and heat. The electron‐donating components of the dendralenes are represented by bromothienyl (in 13 ) and ethylenedioxyt...

The structures of four complexes analyzed by DFT and single‐crystal X‐ray analysis show that, in contrast to free hydrocarbons, complexed dendralenes prefer a roughly in‐plane conformation. The complexes are stable towards Fe(CO)3 group migration up to ...
