Hammett analysis of photodecarbonylation in crystalline 1,3-diarylacetones

(Chemical Equation Presented) The relative quantum yields and chemical efficiencies of crystalline p,p′-disubstituted 1,3-diphenyl-2-propanones with 4-MeO, 4-Me, 4-F, 4-CF3, and 3,4-diMeO groups were determined by parallel irradiation of polycrystalline samples. Variations in quantum yields that span a factor of 4 are analyzed in terms of the effects of substituents on the stability of the benzylic radical. All solid-state reactions proceeded with 100% chemoselectivity and in >95% chemical yield.

HYDROGEN ABSTRACTION FROM THE ISOMERIC CYMENES

The irradiation of cerium (IV) ammonium nitrate in the presence of ortho, meta and para cymene yields products from attack at the methyl group (the nitrates - these ones in 55 to 69percent isolated yield-, the nitro derivatives, and the aldehydes) as well as at the isopropyl group (the acetophenones, not obtained from the ortho isomer), with minimal ring nitration.The formation of bibenzyls on irradiation with t-butyl peroxide of the same substrates is also studied.The mechanisms of the reactions with the NO3 radical, a good electron acceptor, and with the alkoxy radical are contrasted and compared with photochemical hydrogen abstraction by n?* and, respectively, ??* excited states.
