One simple Ir/hydrosilane catalytic system for chemoselective isomerization of 2-substitutedallyl ethers

Here we described one simple Ir/hydrosilane catalytic system for chemoselective isomerization of 2-substitutedallylic ethers. This facile strategy shows high efficiency towards a variety of substrates, including derivatives from bioactive molecules. The substituent at  position of the olefins is supposed to be critical in retarding the alkene hydrosilylation process and leading the reaction to go through the isomerization pathway.
