The catalytic performance of the supported bimetallic nano-particles in the hydrogenation of unsaturated molecules was tested on a wide variety of unsaturated species hex-l-ene, phenyl acetylene, diphenyl acetylene, trans-stilbene, cis-cyclooctene and D-limonene. The highly efficient hydrogenation of hex-1 -ene was accompanied by the isomerisation reaction to cis-and trans-hex-2-ene, which were subsequently hydrogenated (albeit at a much slower rate) as reaction ensued. 

In the radical addition of organic diselenides to acetylenes, diphenyl diselenide adds to electron-deficient acetylenes such as dimethyl acetylenedicarboxylate to form the corresponding vicinal diselenides upon UV-irradiation in benzene (Scheme 15.60) [139]. The procedure cannot, however, be applied to usual alkynes such as 1-octyne. The lower concentration of the substrates might contribute to the inefficiency of the desired radical addition.
