摘要:... 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...

摘要:... 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,...

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.

摘要:Abstract(#br)New [3]‐ and [4]‐dendralenes bearing electron‐donor 1,3‐dithiole and ferrocene substituents have been synthesised. Compounds 8, 15 and 17 have been characterised by single‐crystal X‐ray diffraction. Two of the dithiole rings of 8 are conjugated (dihedra...

摘要:... 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...

摘要:... 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 ...

摘要:The ground state spin multiplicity and the geometry of the reductively and oxidatively doped homo- and heteronuclear dendralenes were investigated by means of ab initio calculations. The results were compared with the calculated effective Heisenberg exchange integral for doped in...

摘要:Abstract(#br)A mild method for the synthesis of highly functionalized [3]–[6]dendralenes is reported, representing a general strategy to diversely substituted higher homologues of the dendralenes. The methodology utilizes allenoates bearing various substitution patterns, alo...

摘要:Abstract(#br)Starting from ( $$Z)$$ -1-trimethylsilyl-3-bromopenta-2,4-diene, a lithium-bromine exchange reaction followed by addition onto carbonyl compounds provided the corresponding dienyl alcohols. A Peterson-type $$\gamma $$ -elimination promoted by a catalytic amount of tr...

摘要:Abstract(#br)A series of [ n ]dendralenes ( n =3, 4, 8, 3b – d ( Fig. 1 )) expanded with buta‐1,3‐diynediyl moieties between the CC bonds were prepared by repetitive acetylenic scaffolding of 3‐(cyclohexylidene)penta‐1,4‐diyne building blocks ( Scheme ). These...
