Rhodium complexes of diazaphospholane ligands catalyze the asymmetric hydroformylation of N-vinyl carboxamides, allyl ethers, and allyl carbamates; products include 1,2- and 1,3-aminoaldehydes and 1,3-alkoxyaldehydes. Using glass pressure bottles, short reaction times (generally less than 6 h), and low catalyst loading (commonly 0.5 mol %), 20 substrates are successfully converted to chiral ald...

We have previously clarified that the strongly electron-withdrawing CF3 group nicely affected base-mediated proton shift of CF3-containing propargylic or allylic alcohols to afford corresponding α,β-unsaturated saturated ketones, respectively, which was applied this time Claisen rearrangement after O-allylation with a group, followed by isomerization allyl vinyl ethers via shift, enabling desir...

Iodonium salts are historical cationic photoinitiators extensively used for the polymerization of epoxides or vinyl ethers. As drawback, absorption iodonium is strongly UV-centered so that this UV photoinitiator can only operate in visible range by mean a photosensitization process. With aim at simplifying composition photopolymerizable resins, numerous chromophores have been covalently linked ...
