Rh-m-TPPTC complex was successful immobilized onto a hydrotalcite Zn-Al to convert selectively in aqueous media both the symmetric and nonsymmetric alkynes into functionalized alkenes, with boronic acids. The complex preserved its activity after the ionic exchange, leading to excellent results (similar to 87%) for the symmetric alkynes and also for the non-symmetrical alkynes (up to 99%).

We report the synthesis of the C84(20)-fullerene related hydrocarbon C84H42, which possesses more than 83% of the C84(20)-fullerene connectivity, and its selective transformation to C84 by flash vacuum pyrolysis (FVP).
