  Thermal rearrangements of 9,10-bis(trifluorovinyl)phenanthrene

  摘要：

  Results from a study of the thermal unimolecular rearrangement of 9,10-bis(trifluorovinyl)-phenanthrene are reported. Kinetic and product studies indicate that it is unexpectedly resistant to rearrangement, that its expected 6pi electrocyclic rearrangement plays but a minor role, and that the major rearrangement process was a virtually unprecedented thermal reaction for 1,3,5-trienes, that of conversion to a bicyclo[3.1.0]hex-2-ene system (7). Activation parameters are provided for the minor electrocyclic process (DELTAH(double dagger) = 29.9 kcal/mol; DELTAS(double dagger) = -19.6 eu) and for the conversion to 7 (DELTAH(double dagger) = 34.4 kcal/mol; DELTAS(double dagger) = -6.6 eu) as well as for the secondary conversions of 7 to 4-(difluoromethylidene)-3,3,5,5-tetrafluoro-1,2-(9,10-phenanthro)cyclopent-1-ene (8) (DELTAH(double dagger) = 31.3 kcal/mol; DELTAS(double dagger) = -12.7 eu) and to 1,2-(9,10-phenanthro)-3,5,5-trifluoro-4-(trifluoromethyl)-1,3-cyclopentadiene (9) (DLETAH(double dagger) = 31.4 kcal/mol; DELTAS(double dagger) = -13.4 eu). A rarely encountered fluorine steric effect deriving from the stringent steric demands of the reaction's boat-like transition state is invoked to explain the inhibition of 1's electrocyclic process, while equally rare thermal 1,2-fluorine atom shifts are proposed to explain the rearrangement of 7.

  were used to assemble precursors to 6π‐electrocyclisations of three different types. Electrocyclisations took place at temperatures between 90 and 240 °C, depending on the central component of the π‐system; nonaromatic trienes were most reactive, but even systems that required the temporary dearomatisation of two arenyl subunits underwent electrocyclisation, albeit at elevated temperatures.

  基于新颖且易于合成的二氟化有机三氟硼酸盐的钯催化偶联反应被用于组装前体，以形成三种不同类型的6π电环化反应。电环化发生在90到240°C的温度之间，具体取决于π系统的中心组成。非芳族三烯具有最高的反应活性，但是即使需要将两个戊基亚基暂时脱芳香化的系统也要进行电环化，尽管温度较高。光化学条件对于这些更苛刻的反应是有效的。该方法包通过灵活的途径提供了结构上多样化的氟化芳烃组，其跨越20kcal mol -1的反应性范围。

  Fluorine substituents have been observed to have a remarkable effect upon the rate and stereochemical outcome of the butadiene-cyclobutene thermal conrotatory 4π-electron electrocyclic interconversion. The substituent effects observed in this system and in other pericyclic systems have enhanced one's understanding of the mechanisms of such reactions, such that only a small probable effect of fluorine
