The photoredox catalytic addition of alcohols to non‐activated terminal alkyl olefins is obtained by the use of N,N‐diisobutylamino‐phenylphenothiazine. Its excited state redox potential is sufficiently high to promote the photoreduction.

Catalytic etherification of diols proceeds to give various cyclic ethers by use of cationic platinum salt, which is in situ prepared from PtCl2 and AgSbF6. Etherification of benzylic alcohols is also possible by intermolecular dehydration. Both of intra- and intermolecular etherifications smoothly proceed even under an atmosphere of air.
