Nafion-catalyzed preparation of benzhydryl ethers

Nafion-H is found to be an efficient and recyclable catalyst for the preparation of diphenylmethyl ethers of alcohols.

Synthesis of indeno[1,2-b]phenanthrene-type heterocycles by cycloaromatization of acyclic non-conjugated benzotetraynes

A novel and simple procedure for the preparation of 6-oxa-, 6-thia-, and 6-azaindeno[1,2-b]phenanthrenes (4) by thermal cycloaromatization of acyclic non-conjugated benzotetraynes (3) is described.

Cycloaromatization of a non-conjugated polyenyne system: Synthesis of 5H-benzo[d]fluoreno[3,2-b]pyrans via diradicals generated from 1-[2-{4-(2-alkoxymethylphenyl)butan-1,3-dinyl}]phenylpentan-2,4-diyn -1-ols and trapping evidence for the 1,2-didehydrobenzene diradical

Non-conjugated tetraynes 1 undergo thermal intramolecular cyclization to non-benzenoid diradicals (23) followed by radical cycloaromatization at 25°C to provide 7-dehydro-5H-benzo[d]fluoreno[3,2-b]pyran monoradical (24) and alkyl radicals (25). Hydrogen abstraction of 24 gives 5H-benzo[d]fluoreno[3,2-b]pyrans (3) which are converted to 4 by reaction with 25. On the other hand, 2 gives 5H-fluorenol (5), indicating the formation of 1,2-didehydrobenzene diradical intermediates (28 and 29). These radicals are trapped as the corresponding Diels-Alder-type products by reaction with an aromatic diene, anthracene.
