Regioselective differentiation of vicinal methylene C-H bonds enabled by silver-catalysed nitrene transfer

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.
Reductive decarboxylation of N-(acyloxy)phthalimides via redox-initiated radical chain mechanism
Okada,Okubo,Morita,Oda

Highly efficient reductive decarboxylation of N-(acyloxy)phthalimides which are readily prepared from carboxylic acids was achieved by visible light irradiation using Ru(bpy)3Cl2 as a sensitizer in the presence of BNAH and t-BuSH via radical chain mechanism.
PHOTODECARBOXYLATION OF UNMODIFIED CARBOXYLIC ACIDS WITH USE OF AZA AROMATIC COMPOUNDS
Okada, Keiji,Okubo, Katsura,Oda, Masaji
, p. 6733 - 6736 (2007/10/02)
A very simple procedure for photodecarboxylation of intact carboxylic acids leading to alkanes is developed with use of aza aromatic compounds as light absorbers and t-BuSH as a hydrogen donor.
