Skeletal reorganisation of benzofused spiro[3.3]heptanes has been achieved using rhodium(i) catalysts. The reaction of benzofused 2-(2-pyridylmethylene)spiro[3.3]heptanes proceeds via sequential C-C bond oxidative addition and β-carbon elimination. On the
Cyclization of (2-alkenylphenyl)carbonyl compounds to polycyclic arenes catalyzed by copper(II) trifluoromethanesulfonate or trifluoromethanesulfuric acid

Various polycyclic arenes, such as naphthalenes, tetrahydroantharacenes, tetrahydrotetracenes, dihydropentacenes, and dihydropentaphenes are prepared from 2-alkenylphenyl ketones and aldehydes by the catalytic use of copper(II) trifluoromethanesulfonate (Cu(OTf)2) or trifluoromethanesulfuric acid (TfOH).

Chelate-assisted oxidative coupling reaction of arylamides and unactivated alkenes: Mechanistic evidence for vinyl C-H bond activation promoted by an electrophilic ruthenium hydride catalyst

The cationic ruthenium hydride complex [(η6-C 6H6)(PCy3)(CO)RuH]+BF 4- was found to be a highly regioselective catalyst for the oxidative C-H coupling reaction of aryl-substituted amides and unactivated alkenes to give o-alkenylamide products. The kinetic and spectroscopic analyses support a mechanism involving a rapid vinyl C-H activation followed by a rate-limiting C-C bond formation step.

An interesting gold-catalyzed electrophilic addition to arylalkyne to synthesize substituted naphthalenes has been presented. Different metal hexafluoroantimonates have also been found to effect the transformation. Counter anion and oxo- and alkynophilicities of catalytic gold species might play an important role in this annulation reaction.

(Figure Presented) A new methodology for the preparation of substituted naphthalenes starting from readily available indenones, organometal reagents, and trimethylsilyldiazomethane via a catalytic rearrangement process is described. Hindered biaryl naphthalenes, including triortho-substituted biaryls, can be accessed through our method. Our results are consistent with a mechanism involving a benzobenzvalene intermediate.
Novel synthesis of 1,3-disubstituted alkyl- and aralkylnaphthalenes from methylenetriphenylphosphorane, 1,1-disubstituted epoxides, paraformaldehyde, and trimethylsilyl triflate

A novel approach toward the synthesis of 3-methylnaphthalenes is achieved by the reaction of 3-methylene-5,5-disubstituted tetrahydrofurans derived from methylenetriphenylphosphorane, 1,1-disubstituted epoxides and paraformaldehyde with trimethylsilyl trifluoromethanesulfonate in the presence of diisopropylethylamine.

, p. 5937 - 5942 (2007/10/03)
Novel cyclopropane-shift type reaction of diaryl(2- halogenocyclopropyl)methanols 2b and 7 proceeded by using BF3·OEt3 and TiCl'4, respectively. Utilizing these reactions, 1-aryl-3-chloro-1,2- methanoindans 5 and 9, 1-aryl-3-methylnaphthalenes 6, and 1,2-methano-1- arylindens 10 were constructed. (C) 2000 Elsevier Science Ltd.
