• Polar effects in free-radical reactions. A novel homolytic acylation of heteroaromatic bases by aerobic oxidation of aldehydes, catalysed by<i>N</i>-hydroxyphthalimide and Co salts

  A new process for the homolytic acylation of protonated heteroaromatic bases is described; an N-oxyl radical (PINO) generated from N-hydroxyphthalimide by air oxygen and Co(II) abstracts a hydrogen atom from an aldehyde. The resulting nucleophilic acyl radical adds to a heteroaromatic base, which is then rearo-matised in a chain process. Quinazoline has an anomalous behaviour, giving 3H-quinazolin-4-one

  描述了质子化杂芳族碱均质酰化的新方法。N-羟基邻苯二甲酰亚胺通过空气氧和Co（II）生成的N-氧基自由基（PINO）从醛中提取氢原子。所得的亲核酰基基团加到杂芳族碱基上，然后在链状过程中重新构型。喹唑啉具有异常行为，给出3 H-喹唑啉-4- 1是唯一的反应产物。

  conditions. Spectroscopic investigations such as steady state fluorescence quenching and dynamic lifetime quenching experiments were employed to better understand the role of Eosin Y as both a photoredox catalyst and a photoacid. Feedstock aldehydes were employed as acyl radical precursors for engaging in C–C bond formation reactions with a variety of nitrogen containing heterocycles.

  A novel heterocyclic compound is provided. In particular, a novel heterocyclic compound which can improve the element characteristics of the light-emitting element is provided. The heterocyclic compound is represented by a general formula (G1) DBq-(Ar 1 )- n -Ar 2 -A   (G1) in which a substituted or unsubstituted dibenzo[f,h]quinoxalinyl group and a substituted or unsubstituted benzobisbenzofuranyl group are bonded to each other via a substituted or unsubstituted arylene group. In the general formula (G1), DBq represents a substituted or unsubstituted dibenzo [f,h] quinoxalinyl group, Ar 1 represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms, n represents 0 or 1, Ar 2 represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms, and A represents a substituted or unsubstituted benzobisbenzofuranyl group. When the arylene group represented by Ar 1 and Ar 2 has substituents, the substituents may be bonded to each other to form a ring.
