    摘要:
    烷基,芳基和杂原子取代的环丙烯酮的UV照射导致一氧化碳损失并形成相应炔烃的定量收率。光化学脱羰反应的量子产率从烷基取代的环丙烯酮的20%到30%到二苯基和二萘基环戊烯酮的70%以上。通过使用激光闪光光解法观察到该反应中中间体迅速形成(<5 ns),然后稍微慢一些(约40 ns)衰变。DFT计算使我们能够将这种中间体鉴定为由环丙烯酮环的碳-碳键之一裂解形成的两性离子物质。后者然后迅速损失一氧化碳以产生最终的炔属产物。尽管它们的光反应性很高,除羟基和甲氧基取代的环丙烯酮外,发现环丙烯酮是热稳定的化合物。后者甚至在室温下也能在羟基溶剂中进行快速溶剂分解。该反应对苯二炔结构原位生成的应用通过苯并二烯化的苯二炔12的光化学制备进行了说明。

  • Photonic Amplification by a Singlet-State Quantum Chain Reaction in the Photodecarbonylation of Crystalline Diarylcyclopropenones
    作者:Gregory Kuzmanich、Matthew N. Gard、Miguel A. Garcia-Garibay

    日期:2009.8.19
    The photochemical decarbonylation of diphenylcyclopropenone (DPCP) to diphenylacetylene (DPA) proceeds with remarkable efficiency both in solution and in the crystalline solid state. It had been previously shown that excitation to the second electronic excited state (S-2) of DPCP in solution proceeds within ca. 200 fs by an adiabatic ring-opening pathway to yield the S-2 state of DPA, which has a lifetime of ca. 8 ps before undergoing internal conversion to S-1(Takeuchi, S.; Tahara, T. J. Chem. Phys. 2004, 120, 4768). More recently, we showed that reactions by excitation to S-2 in crystalline solids proceed by a quantum chain process where the excited photoproducts transfer energy to neighboring molecules of unreacted starting material, which are able to propagate the chain. Quantum yields in crystalline suspensions revealed values of Phi(DPCP) = 3.3 +/- 0.3. To explore the generality of this reaction, and recognizing its potential as a photonic amplification system, we have synthesized nine crystalline diarylcyclopropenone derivatives with phenyl, biphenyl, naphthyl, and anthryl substituents. To quantity the efficiency of the quantum chain in the crystalline state, we determined the quantum yields of reaction for all of these compounds both in solution and in nanocrystalline suspensions. While the quantum yields of decarbonylation in solution vary from Phi = 0.0 to 1.0, seven of the nine new structures display quantum yields of reaction in the solid that are above 1. The chemical amplification that results from efficient energy transfer in the solid state, analyzed in terms of the quantum yields determined in the solid state and in solution (Phi(cryst)/Phi(soln)), reveals quantum chain amplification factors that range from 3.2 to 11.0. The remarkable mechanical response of the solid-to-solid reaction previously documented with macroscopic crystals, where large single-crystalline specimens turn into fine powders, was investigated at the nanometer scale. Experiments with dry crystals of DPCP analyzed by atomic force microscopy showed the formation of DPA in the form of isolated crystalline specimens ca. 35 nm in size.
