An Organocatalytic System for <i>Z</i>‑Alkene Synthesis via a Hydrogen-Bonding-Assisted Photoinduced Electron Donor–Acceptor Complex
A general
catalytic donor for the combination of a photoinduced
electron donor–acceptor (EDA) complex and energy transfer was
developed. This mild and metal-free protocol allows facile access
to various Z-alkenes. Mechanism studies revealed
that the organophotocatalyst, 4-CzIPN, formed a distinct three-component
EDA complex with redox-active esters and (C6H5O)2P(O)OH to trigger the photoredox catalysis. The E → Z isomerization was achieved
via electron exchange energy transfer from 4-CzIPN
