Abstract:
The photocatalyzed (350 nm) isomerization of linear olefins catalyzed by platinum(II) bis(acetylacetonato) [Pt(acac)(2)] in the presence of silanes was studied. Catalytic activity depends on the silane. Triphenylsilane is the most reactive silane studied, with more than 98% isomerization of the alkene occurring after 20-min irradiation. There is no concomitant hydrosilylation. The mechanism has been investigated and a metal hydride addition-elimination mechanism proposed.
