  Preparation of Benzolactams by Pd(OAc)₂-Catalyzed Direct Aromatic Carbonylation

  摘要：

  We developed a new method for Pd(II)-catalyzed direct aromatic carbonylation in a phosphine-free catalytic system using Pd(OAc)2 and Cu(OAc)2 in an atmosphere of CO gas containing air. The carbonylation proceeded with ortho-palladation, inducing a remarkable site selectivity to afford a variety of five- or six-membered benzolactams from secondary omega-arylalkylamines, such as N-alkylbenzylamines or N-alkylphenethylamines.

• A Latent Reaction in a Model GFP Chromophore Revealed upon Confinement: Photohydroxylation of <i>ortho</i>-Halo Benzylidene-3-methylimidazolidiones via an Electrocylization Process

  Excited state behavior of halogen substituted model GFP chromophores was investigated in an acetonitrile solution and in a confined environment provided by an octa acid capsule in water. Of the ortho, meta, and para halogen substituted GFP chromophores only the ortho compounds gave a new product resulting from an unprecedented photosubstitution of halogens by the hydroxyl group. This unusual reaction

  在乙腈溶液中以及在辛酸胶囊在水中提供的密闭环境中，研究了卤素取代的GFP型发色团的激发态行为。在邻位，间位和对位卤素取代的GFP生色团中，仅邻位化合物会产生新产物，这是由于卤素通过羟基空前的光解而产生的。这种不寻常的反应凸显了密闭空间在实现某些无法实现的光反应中的重要性。
• Separation of Ring Polar and Resonance Effects on the Rate Constants for Uncatalyzed N-Arylidenepropylamine Formation in Methanol

  Rate constants are reported for the reaction of a series of 19 ring-substituted benzaldehydes with propylamine in methanol and in O-d-methanol at different temperatures and of three of them with 2-methoxyethylamine and 2,2-dimethoxyethylamine. The large direct solvent kinetic isotope effects (KSIE) (2.1-2.9), as well as the Delta H* (4.7-7.6 kcal mol(-1)) values vary smoothly with substituent. Delta S* (ca. -45 cal mol(-1) K-1) is almost independent of substituent. These data indicate that there in no change in the rate-limiting step, and since the large KSIE and \Delta S*\ can be related to significant solvation of the leading OH- group at the transition state, they agree with a mechanism involving cu-amino alcohol formation in a fast preequilibrium followed by rate-limiting OH- detachment yielding iminium ions. When corrected for parallel hemiacetal formation, the second-order rate constants are accounted for by the Young-Jencks equation with p(n) = 0.08 and p(r) = 0.57, this equation allowing a separation of the direct resonance effects from the polar effects of the substituted ring. The very low p(n) value indicates that the polar effects for the rate-limiting OH- detachment are almost compensated by those on the constant of the alpha-amino alcohol-formation preequilibrium. In contrast, the relatively large p(r) coefficient, which means that the overall rate constants depend almost exclusively on resonance, is due to predominance of the direct resonance effects on the preequilibrium. The KSIE and Delta S* data, as well as the beta(nucl) parameters (close to unity) observed when the reacting amine was changed (slopes of the straight lines obtained by plotting the logarithm of the rate constants vs the pK(a) of the ammonium ions) favor a late transition state. In contrast, the low p(r) value for the rate-limiting step (ca. -0.5) shows that the transition state is not iminium ion-like.
