Alkynyl halides in ruthenium(II)-catalyzed [2+2] cycloadditions of bicyclic alkenes
Allen, Anna,Villeneuve, Karine,Cockburn, Neil,Fatila, Elisabeth,Riddell, Nicole,Tam, William
experimental part, p. 4178 - 4192 (2009/05/27)
Ru-catalyzed [2+2] cycloadditions between bicyclic alkenes and alkynyl halides were found to occur in moderate to good yields. The presence of the halide moiety greatly enhances the reactivity of the alkyne component in the cycloaddition and can be transformed into a variety of products that are difficult or impossible to obtain by direct cycloaddition.

Ruthenium-catalyzed [2+2] cycloadditions of alkynyl sulfides and alkynyl sulfones

Ruthenium-catalyzed [2+2] cycloadditions of bicyclic alkenes with alkynyl sulfides and alkynyl sulfones were investigated. The sulfide and sulfone moieties were found to be compatible with the Ru-catalyzed cycloadditions, giving the corresponding cyclobut

Phenyl(arylsulphonyl)acetylenes 1a and 1b react with olefins and dienes to give the addition products of the two fragments derived from the acetylenic carbon-sulfur bond scission.In the reaction with dienes, the and cycloadducts are also forme
