Selective direct ruthenium-catalyzed semihydrogenation of diaryl alkynes to the corresponding E-alkenes has been achieved using alcohols as the hydrogen source. The method employs a simple ruthenium catalyst, does not require external ligands, and affords the desired products in > 99% NMR yield in most cases (up to 93% isolated yield). Best results were obtained using benzyl alcohol as the hydrogen donor, although biorenewable alcohols such as furfuryl alcohol could also be applied. In addition, tandem semihydrogenation-alkylation reactions were demonstrated, with potential applications in the synthesis of resveratrol derivatives.
Metallation of alkynes: Part 10. Acetoxymercuration of arylferrocenylethynes
Carollo, Lorenzo,Floris, Barbara
, p. 80 - 85 (2007/10/03)
Arylferrocenylhethynes compounds reacted with mercuric acetate in acetic acid yielding mercurated addition compounds, the regiochemistry of which were determined by the strongly electron-donating ferrocenyl ring. Substituent effects on the reactivity are
