A p-toluenesulfonic acid catalyzed fluorination of α-branched ketones for the construction of fluorinated quaternary carbon centers has been developed, featuring a broad substrate scope, environmentally benign reaction conditions, and operational simplicity.

In the photoreactions of 3-(2-oxocyclohexyl)-propionicacid derivatives a pronounced effect of fluorine substitution is found on the ratio of a) Norrish II vs. Norrish I products; b) cyclization vs. cleavage of the Norrish II biradical; c) ketene vs. unsaturated aldehyde formation from the Norrish I biradical.
