Satyajit Haldar Subratanath Koner Department of Chemistry, Jadavpur University, Kolkata 700032, India 10.3762/bjoc.9.6 Abstract The addition of phenols to aryl-substituted alkynes to form 1,1-diarylalkenes was carried out by using the Fe-Al-MCM-41 catalyst. The catalyst showed remarkable
improvement in time and yield in comparison to other solid catalysts. The heterogeneous catalyst can be reused at least three times without a significant loss in activity.
Keywords: 1,1-diarylalkenes; heterogeneous catalysis; Fe-Al-MCM-41; Introduction
The direct vinylation of phenols has received
corresponding 1,1-diarylalkenes in high conversion and selectivity within a short reaction time.
Furthermore, to verify whether the coupling reaction was truly catalyzed by solid Fe-Al-MCM-41 or by the leached iron species from the solid support, a “hot filtration” experiment was undertaken. A reaction between
