  摘要：

  母体和对硝基苯基取代的双自由基D-3a，b（三重峰），四自由基T-3a，b（五重峰）和六自由基H-3a，b（九重峰）以基质分离的形式（甲苯，77 K）通过三偶氮烷3a，b的连续脱氮和EPR进行光谱表征。在这些高自旋多自由基中，局部自旋携带的1，3-环戊二基二自由基单元中的自旋-自旋相互作用比交叉共轭铁磁耦合单元中的自旋-自旋相互作用强得多。因此，环戊二基单元中电子性质的变化决定性地影响整个多自由基的D值。因此，自旋接受的对硝基基团以与双自由基相同的量减少四和六自由基的D值。因此，无论自旋多重性如何，

• 1,4-Carbonyl participation in solvolysis of alkyl toluene-p-sulphonates
  作者：Philip K. G. Hodgson、Stuart Warren

  DOI：10.1039/p29750000372

  日期：——

  2,2-Dimethyl-3-oxo-3-phenylpropyl toluene-p-sulphonate (tosylate) and some related 3-oxoalkyl tosylates are solvolysed in buffered carboxylic acid solvents by 1,4-carbonyl participation to give unrearranged carboxylate esters. The reactions are too fast to be direct displacements, and do not occur in similar compounds which lack the carbonyl group. Secondary alkyl tosylates in the same series also

• Selective Aldehyde Reduction in Ketoaldehydes with NaBH₄-Na₂CO₃-H₂O at Room Temperatures
  作者：Sosale Chandrasekhar、Annadka Shrinidhi

  DOI：10.1080/00397911.2014.888751

  日期：2014.7.18

  A variety of aliphatic and aromatic ketoaldehydes were reduced to the corresponding ketoalcohols with a mixture of sodium borohydride (1.2 equivalents) and sodium carbonate (sixfold molar excess) in water. Reactions were performed at room temperatures over (typically) 2 h, and yields of isolated products generally ranged from 70% to 85%. A biscarbonate-borane complex, [(BH3)(2)CO2](2-) 2Na(+), possibly formed from the reagent mixture, is likely the active reductant. The moderated reactivity of this acylborane species would explain the chemoselectivity observed in the reactions. The readily available reagents and the mild aqueous conditions make for ease of operation and environmental compatibility, and make a useful addition to available methodology.
