  Molecular Structures and Photochemical Behavior of Doubly Bridged Prismanes

  摘要：

  The molecular structures of four prismanes were determined by X-ray analysis. The diester derivatives 1a, 1b, and 3 show a lengthening of the vicinal bonds and a shortening of the distal bonds in the cyclopropane moieties, whereas in bis(hydroxymethyl) compound 2 no significant bond length differences were found. These structural properties affect their chemical behavior: if prismanes la and Tb are irradiated with UV light a selective cleavage of the elongated cyclopropane bonds affords exclusively Dewar benzenes 4a and 4b as primary products whereas from 2 both possible isomeric Dewar benzenes 8 and 9 are obtained.

• Synthesis of doubly bridged prismanes: an investigation of the photochemical behavior of doubly bridged Dewar benzenes

  日期：1993.12

  Starting from cyclic acetylenes, two stereoisomeric doubly bridged Dewar benzenes of type 14 and 15 were synthesized, and the effects of the chain length and the nature of two other functional groups on their photochemical behavior were examined. The isomers with bridges spanning the 1,4- and 2,3-positions, 14b,c and 25b, reacted to form the respective prismanes, 17b,c and 27b. Isomers 15b-d, with bridges spanning the 1,2- and 3,4-positions, revealed a more complex photochemistry. through consecutive transposition reactions via a total of five intermediates, an unexpected phthalic/terephthalic ester rearrangement was observed. Prismane 38b and Dewar benzenes 39b,c could be characterized directly, and the existence of the other intermediates was deduced indirectly.
