Photocatalytic One-Pot Synthesis of Homoallyl Ketones via a Norrish Type I Reaction of Cyclopentanones
A photocatalytic synthesis of homoallyl
ketones was achieved via
a one-pot procedure starting from a Norrish Type I reaction of cyclopentanones,
followed by a decatungstate-catalyzed hydroacylation of electron-deficient
olefins by the resulting 4-pentenals. The site-selective formyl H-abstraction
in the second step can be explained by radical polar effects in the
transition state
Photocatalyzed Site-Selective C–H to C–C Conversion of Aliphatic Nitriles
β- or γ-Site-selective
C–H alkylation of aliphatic
nitriles has been achieved using a decatungstate salt as the photocatalyst.
The observed site selectivity was justified by a radical polar effect
in transition states for hydrogen abstraction
