  摘要：

  1-(2-乙氧基羰基乙烯基)苯并三唑的快速真空热解已被重新研究，并导致形成乙基吲哚-3-羧酸酯和2-乙氧基喹啉-4(1H)-的过程得到阐明。在相应的苯并异恶唑酮的闪蒸真空热解中遵循类似的途径。一些N-乙烯基异恶唑酮已被热解形成吡咯，但可以观察到中间体卡宾的重排。异恶唑酮的光解产生可以被溶剂捕获的卡宾或产生吡咯。

  Described are compositions of at least one material represented by a pyrano[3,2-c]quinoline structure, a pyrano[3,2-c]quinolinone structure or mixtures thereof. The pyrano[3,2-c]quinoline structure is characterized by having a nitrogen atom at the 6-position ring atom and an oxy-substituent at the 5-position ring atom. The pyrano[3,2-c]quinolinone structure is characterized by having a substituted nitrogen atom at the 6-position ring atom and an oxo-substituent at the 5-position ring atom, the nitrogen atom substituents being hydrogen, aliphatic substituents, cycloaliphatic substituents, aromatic substituents, heteroaromatic substituents or a combination thereof. Both of the pyrano[3,2-c]quinoline and pyrano[3,2-c]quinolinone structures are characterized by having two substituents at the 2-position ring atom, each substituent being independently chosen from aliphatic substituents, cycloaliphatic substituents, aromatic substituents, heteroaromatic substituents or a combination thereof, provided that both substituents at the 2-position are not aliphatic. Alternatively, the two substituents at the 2-position can combine to form a spirocyclic group, provided that the spirocyclic group is not norbornylidene or bicyclo[3.3.1]9-nonylidene. The ring atoms have been numbered according to the International Union of Pure and Applied Chemistry rules of nomenclature starting with the 1-position ring atom being the oxygen atom of the pyran ring and numbering counterclockwise therefrom. Also described are photochromic articles that contain or that have coatings or films containing at least one of the novel compositions or combinations thereof with other photochromic materials.
