• Copper-catalyzed homolytic and heterolytic benzylic and allylic oxidation using tert-butyl hydroperoxide

  日期：——

  Allylic and benzylic alcohols were oxidized in good yields to the respective ketones by tert-butyl hydroperoxide (TBHP) in the presence of copper salts under phase-transfer catalysis conditions. This dehydrogenation was found to proceed via a heterolytic mechanism. CuCl2, CuCl, and even copper powder were equally facile as catalysts, as they were all transformed in situ to Cu(OH)Cl which was extracted

  在相转移催化条件下，在铜盐存在下，叔丁基氢过氧化物（TBHP）将烯丙醇和苄醇以良好的产率氧化为相应的酮。发现该脱氢是通过杂化机理进行的。CuCl 2，CuCl甚至铜粉同样容易用作催化剂，因为它们都可以原位转化得到Cu（OH）Cl，其被相转移催化剂（PTC）萃取到有机相中。氘标记实验证明了在速率测定步骤中苄基CH键的断裂。在醇底物的存在下未观察到非生产性TBHP分解。相反，发现在同一介质中的π-活化的亚甲基的氧合是一个自由基过程，主要产物是合适的叔丁基过氧化物。讨论了催化剂的失活，溶剂作用和萃取作用。通过应用的Minisci的关于TBHP分子朝着相对反应性的假定叔-质子和非质子环境中的-丁氧基自由基，可以解释均解和杂化途径的共存。提出了一种完整的反应机理，其中自由基氧化遵循高知的机理，并且杂合脱氢基于高价Cu IV O物种或[Cu（OH）Cl] 2物种。

  conditions (solvent, base, temperature and oxidant) for allylic and benzylic oxidation reactions catalyzed by dirhodium(II)/N-heterocyclic carbene (NHC) complexes were optimized for the first time in this work. The oxidations of cyclohexene and fluorene were used as model reactions. Two optimized experimental conditions for both types of oxidations were found, which resulted in their ketone [aerobic conditions

• Electronic Absorption Spectra of Some Alkoxyl Radicals. An Experimental and Theoretical Study

  The visible and UV absorptions of a variety of alkoxyl radicals have been examined by experiment and theory. In most solvents, the tert-butoxyl radical shows only a weak ''tail-end'' absorption in the UV region of the spectrum and no absorption in the visible region. However, a visible absorption band has been observed (lambda(max) = 440 nm) in the presence of 1,3,5-trimethoxybenzene. This absorption band provides the first unequivocal evidence for the existence of alkoxyl radical/electron-rich aromatic pi-complexes. By way of contrast, a solvent-independent absorption in the visible is observed for (arylcarbinyl)oxyl radicals, e.g., benzyloxyl (lambda(max) = 460 nm, epsilon = 1300 M(-1) cm(-1)) and cumyloxyl (lambda(max) = 485 nm, epsilon = 1300 M(-1) cm(-1)). Electron-donating substituents on the aromatic ring shift the visible absorption to the red by 25-30 nm for a 4-methyl group and by 100-105 nm for a 4-methoxy group. However, alpha-substitution has only a minor effect on lambda(max), e.g., 530 and 535 nm for diphenylmethoxyl and 1,1-diphenylethoxyl, respectively. The visible absorption appears to be virtually uninfluenced by the (calculated) magnitude of the dihedral angle, theta, between the C-O-. bond and the plane of the aromatic ring, e.g., indan-1-oxyl, theta - 51 degrees, lambda(max) = 530 nm, and Tetralin-1-oxyl, theta similar to 33 degrees (major conformer), lambda(max) = 520 nm, vs benzyloxyl and cumyloxyl, both of which have theta similar to 0 degrees. All of these experimental observations are well-matched by theory, which reveals that the visible absorptions of (arylcarbinyl)oxyl radicals are due to D-0(A '')-->D-2(A '') (pi-->pi*) transitions which increase the negative charge on the oxygen atom and have respectable oscillator strengths. The unpaired electron is largely localized in the oxygen 2p orbital which is perpendicular to the plane of the aromatic ring.
