Isomerization of 7-oxabenzonorbornadienes into naphthols catalyzed by [RuCl(2)(CO)(3)](2).
Ruthenium-catalyzed isomerization of 7-oxanorbornadienes into naphthols was investigated. Among the various ruthenium catalysts tested, [RuCl(2)(CO)(3)](2) gave the highest yields in theExpand

1,3-Dipolar cycloaddition of nitrile oxides with unsymmetrically substituted norbornenes
Abstract 1,3-Dipolar cycloadditions of nitrile oxides with unsymmetrically substituted norbornenes were investigated. The cycloadditions were found to be completely stereoselective, giving only theExpand

Ring strain energies: substituted rings, norbornanes, norbornenes and norbornadienes
Abstract Ring strain energies (RSEs) are predicted using homodesmotic reactions at the B3LYP/6-31G * level of theory. Substituents are conserved in the acyclic reference and any difference in energyExpand

Ruthenium-catalyzed [2 + 2] cycloadditions of ynamides.
Ruthenium-catalyzed [2 + 2] cycloadditions between norbornene and ynamides were investigated. The ynamide moiety was found to be compatible with the ruthenium-catalyzed cycloaddition conditions,Expand

Rhodium-catalyzed intramolecular [4 + 2] cycloadditions of alkynyl halides.
[reaction: see text] Cationic rhodium(I)-catalyzed intramolecular [4 + 2] cycloadditions of diene-tethered alkynyl halides were found to occur in good yields (70-87%). The halide moiety is compatibleExpand

Ruthenium-catalyzed [2 + 2] cycloadditions between bicyclic alkenes and alkynyl halides.
Ru-catalyzed [2 + 2] cycloadditions between norbornadiene and alkynyl halides were found to occur in moderate to good yields (32-89%). The presence of the halide moiety greatly enhances theExpand
