Visible-light-mediated photocatalytic cross-coupling of acetenyl ketones with benzyl trifluoroborate

In this report, we describe a simple visible light-triggered Barbier-type reaction by employing acetenyl ketones with benzyl trifluoroborates. Through a radical-radical cross-coupling process, this photocatalytic protocol furnished a wide range of tertiary propargyl alcohols. Mechanistic investigation indicated that proton-coupled electron transfer (PCET) might be involved in the photochemical transformations.

AUTOOXIDATION OF ACETYLENES AND THEIR DERIVATIVES. XXV. 1-PHENYL-4-PENTEN-1-YN-3-0L AND 1-PHENYL-4-HEXEN-1-YN-3-OL

During the autooxidation of secondary enynyl alcohols attack by oxygen takes place at the C-H bonds at the α position to the triple and double bonds and the hydroxyl group.The initially formed unstable hydroxyhydroperoxides dissociate under the oxidation conditions into the corresponding enynyl ketones, acetylenic keto epoxydes, and products from degradation of the carbon skeleton.
