  了解溶剂化：Reichardt的溶剂变色探针与相关分子“核心”结构的比较

  摘要：

  化合物2,6-二苯基-4-（2,4,6-三苯基吡啶-1-基）酚盐p -RB在不同溶剂中显示不同的颜色（溶剂变色）。化合物4-（吡啶-1-基）苯酚盐，p -CB代表p -RB的部分，该部分是造成这种现象的原因。我们比较了两种化合物以及与结构相关的2-（吡啶-1-基）酚盐，邻-CB和（2,4-二甲基-6-（2,4,6-三苯基-N-吡啶- 1-yl）phenolate，o -RB。在纯溶剂中，经验溶剂极性参数[ E T（探针），不同探针的kcal / mol]与接近于一的斜率线性相关。也就是说，这些探针对与溶剂的特异性和非特异性相互作用同样敏感。在水与二甲基亚砜（DMSO）和1-丙醇（1-PrOH）的二元混合物中，首次研究了p -CB和o -CB的溶剂溶变色。由于探针被二元溶剂混合物的一种组分优先溶剂化，因此E T（探针）对混合物组成的依赖性不理想。我们使用考虑了复杂溶剂[HOH···O═S（CH

  Reactions of 4-oxocyclohexa-2,5-dienylidene (1) and two derivatives have been investigated using laser flash photolysis techniques. Photolysis of 4-diazocyclohexa-2,5-dien-1-one (4) in 1,1,2-trichlorotrifluoroethane allows the indirect detection of the corresponding carbene 1. This carbene reacts with triplet oxygen at close to the diffusion-controlled rate, forming the carbonyl 0-oxide (lambda(max) = 470 nm). Reaction of triplet 1 with moderate concentrations of cyclohexane leads to formation of phenoxyl radical (lambda(max) = 395 nm). At high concentrations or in neat cyclohexane the predominant path appears to be carbene insertion into the C-H bond. Other reactions examined include 0-H insertion in methanol and the indirect formation of ylides from acetone, acetonitrile, and pyridine. The reactivity pattern that emerges indicates that carbene 1 and its derivatives, 2 and 3, have triplet ground states and that the singlet-triplet energy gap is moderately large. Ylide formation is only observed when the reactants are present in low concentrations and involve a two-step reaction from the triplet carbene; no ylides are observed in neat acetone or acetonitrile suggesting that for the singlet carbene insertion into C-H bonds is favored over direct ylide formation.
