Silver-catalyzed nitrene insertion enables the formation of benzosultams in good yield and with regioselectivity complementary to other transition metal nitrene-transfer catalysts. Preferential formation of six-membered benzosultam rings predominates for alkyl-substituted benzenesulphonamide precursors. Ligand-controlled tunability is also achieved for benzenesulphonamides with γ-branched alkyl substituents. Mechanistic probes suggest that the reaction pathway differs depending on whether a α (benzylic) or β (homobenzylic) C-H bond undergoes amidation, as well as the catalyst identity.
Photoelectron Spectra of Paracyclophane and Paracyclophane-4-ene. An Estimation of Inductive and Hyperconjugative Effect for Paracyclophanes

Based on the split of the first two bands in the photoelectron(PE)spectra of paracyclophane, paracyclophane-4-ene, 1,4-di-n-butyl-, 1,4-di-n-propyl- and 1,4-diethylbenzene as well as p-xylene it is shown that the inductive and hyperconjugative effec
