Figure 1. Bond Dissociation Energy of sp3C-H bonds。 最近,扬州大学贾晓东教授课题组报道了以自由基正离子盐为引发剂,通过分子内自由基1,6氢迁移形成七元过渡态的历程,实现了由活性到惰性C-H键的接力氧化活化,成功的构筑了靛红骨架。实验结果表明,该反应具有较好的底物适应性和官能团兼容性。该课题组从分子内的...
The high strain energy of cyclopropene (54.1 kcal/ mol) is attributed largely to angular strain. The anomalously low SE of cyclobutene relative to cyclobutane (DeltaSE = 4 kcal/mol) is a consequence of normal C-H bond dissociation energies for cyclobutane (100.6 kcal/mol) and very strong ...
C–H bonds are ubiquitous but considered very inert due to high bond energy and rather similar bond-dissociation energy in C–H bonds [[8], [9], [10], [11], [12]]. As a result, selective activation and transformation of C–H bonds is a very challenging reaction in organic synthesis...
