(Chemical Equation Presented) There have been a number of reports of the kinetic conjugate (1,4) addition of metalated arylacetonitriles to enones. Several proposals have been made to explain this behavior based on nucleophile structure or aggregation state or on the HSAB properties of the reactants. A reexamination of these studies showed that in each case the 1,4 adducts resulted from equilibration of the kinetically formed 1,2 adducts to the more stable 1,4 adducts. Thus, no conclusions about the origins of 1,4 selectivity can be drawn from these experiments. The 1,2 addition, retro-1,2 addition, 1,4 addition, and retro-1,4 addition of lithiophenylacetonitrile to benzylideneacetone were examined, and a free energy level diagram was constructed for the reaction.

A series of pyrethroid model esters with various substituents in the acid or alcohol moiety have been irradiated by u. v.-radiation (λ > 220 nm).The main reaction is decarboxylation, as evidenced by gas chromatographic (g. c.) and mass spectrometric (m. s.) analyses.In the photoinduced decarboxylation reaction, the substituent effect on the main transition, which occurs via carbonyl excitation, and on the reactivity of a radical intermediate have been examined by semiempirical molecular-orbital calculations (MNDO and CNDO/S).It has been found tha the change of benzyl carbon-oxygen bond strength in the excited states is one of the important factors in determining the yield of the decarboxylated product.
