One-pot synthesis of α-methyl ketones starting from 1,3-diaryl propenols or 1-aryl propenols and methanol as a C1 source is demonstrated. This one-pot isomerization-methylation is catalyzed by commercially available Pd(OAc)2 with H2O as the only by-product. Mechanistic studies and deuterium labelling experiments indicate the involvement of isomerization of allyl alcohol followed by methylation through a hydrogen-borrowing pathway in these isomerization-methylation reactions.
Long-Range Triplet Hydrogen Abstraction. Photochemical Formation of 2-Tetralols from β-Arylpropiophenones

The four ketones β-(o-tolyl)- and β-mesitylpropiophenone and -isobutyrophenone all undergo photocyclization to 2-tetralols via triplet-state ε-hydrogen abstraction.The intermediate 1,6-biradicals cyclize in 100percent efficiency.The triplets react in very
