o-Quinonoid heterocycles: Benzo[c]tellurophene
Morkved, Eva H.,Lakshmikantham,Cava, Michael P.
, p. 9149 - 9150 (1996)
The first synthesis of the o-quinonoid heterocycle benzo[c]tellurophene (5) has been achieved. Compound 5, prepared in two steps from the known 1,3-dihydrobenzo[c]tellurophene diiodide (6), was characterized spectroscopically, and by Diels-Alder trapping reactions.
Palladium-catalyzed tandem Heck and aldol reactions between 2-bromobenzaldehydes and functionalized alkenes leading to naphthalenes
Cho, Chan Sik,Lim, Dong Kwon,Zhang, Jiao Qiang,Kim, Tae-Jeong,Shim, Sang Chul
, p. 5653 - 5656 (2004)
2-Bromobenzaldehydes react with an array of suitably functionalized alkenes in the presence of a catalytic amount of a palladium catalyst together with a base to afford the corresponding naphthalenes in moderate to good yields.
Gold-Catalyzed Ring Expansion of Enyne-Lactone: Generation and Transformation of 2-Oxoninonium
Luo, Kui,Cao, Tongxiang,Jiang, Huanfeng,Chen, Lianfen,Zhu, Shifa
supporting information, p. 5856 - 5859 (2017/11/10)
An efficient gold-catalyzed ring-expansion reaction of enyne-lactones to form 2-oxoninonium intermediates is reported. The 2-oxoninonium generated in this work could undergo further 6π electrocyclization and aromatization reaction to produce different aromatic compounds.
EPR Studies on Carboxylic Esters. Part 15. Spin Density Distribution in the Radical Anions of Naphthalenecarboxylic Esters
Strey, Karsten,Voes, Juergen
, p. 648 - 682 (2007/10/03)
Persistent radical anions of naphthalene mono-, di-, and tetracarboxylic esters are generated by in situ electroreduction.The spin density distribution is determined from the proton hfs coupling constants as measured by EPR spectroscopy and is discussed in terms of semi-empirical MO calculations.
