    摘要:
    二丙基二嗪在二氯甲烷中于4°C进行的光解(350 nm)产生E和Z 3-庚烯的混合物,产率为81%,比率为1.8。形成的四丙嗪的产率低于5%。在哌啶存在下二丙基二嗪碱的光解导致形成卡宾-胺加合物。在0.06 M哌啶的存在下,加合物的收率为48%,E和Z 3-庚烯的收率为47%,而3-庚烯的比例为1.1。结果表明,庚烯是由三个途径形成的。一个途径涉及直接由二嗪生成的二丙基卡宾,其他途径归因于4-重氮庚烷的离子和光化学反应以及归二嗪前体的激发态。用一个简单的捕集阱可以很容易地截获二丙基卡宾。该方法的产率受到前体形成卡宾的效率的限制。

  • Photolysis of dipropyldiazirine and trapping of dipropylcarbene with piperidine

    pathway involves dipropylcarbene formed directly from the diazirine, the other pathways are attributed to ionic and photochemical reactions of 4-diazoheptane and to the excited state of the diazirine precursor. Dipropylcarbene can be easily intercepted with a simple trap. The yield of this process is limited by the efficiency with which the precursor forms the carbene.

  • Chemistry and Kinetics of Dipropylcarbene in Solution

    The photochemistry of 2-methoxy-2-methyl-5,5-dipropyl-Delta(3)-1,3,4-oxadiazoline (1a) and 2,2-dimethoxy-5,5-dipropyl-Delta(3)-1,3,4-oxadiazoline (1b) was investigated. Photolysis (300 nm) of these compounds in solution leads to fragmentation to 4-diazoheptane (major), which slowly forms the corresponding azine. Fragmentation to form 4-heptanone is also observed. Yields of 4-diazoheptane in CH2Cl2 are much larger than those in pentane. 4-Diazoheptane can be trapped with 1-pentene to form a pyrazoline or with methanol to form 4-methoxyheptane. The pyrazoline can be decomposed photochemically to form 1,1,2-tripropylcyclopropane. In solution, 4-diazoheptane is inefficiently photolyzed to dipropylcarbene (DPC), which can be trapped with piperidine or with pyridine in laser flash photolysis experiments. Analysis of the piperidine and pyridine data indicates that the lifetime of DPC in cyclohexane, methylene chloride, or Freon-113 (CF2ClCFCl2) solution at ambient temperature is controlled by 1,2 hydrogen migration to form Z- and E-3-heptene. The lifetime deduced under these conditions is approximate to 300 ps, which is about 20-fold shorter than that of dimethylcarbene in perfluorohexane at ambient temperature. Upon photolysis (254 nm) of oxadiazoline 1a in argon, 4-diazoheptane and 1-methoxydiazoethane are formed. These diazo compounds undergo subsequent photolysis that revealed the formation of methoxy(methyl)carbene and E- and Z-3-heptene. It was not possible to detect DPC in argon at 14 K.
