Abstract
Photofragmentation of substituted 1-methylene-1,2,2a,10b-tetrahydrocyclobuta[]phenanthrenes, under ambient conditions in solution, produces the corresponding allenes with the concomitant formation of phenanthrene. These phenanthrene-based precursors offer a new and general photochemical route to allenes including, potentially, strained cyclic allenes.
摘要
在溶液中的环境条件下，取代的1-亚甲基-1,2,2a,10b-四氢环丁烷并[ ]菲的光碎片化反应生成相应的丙二烯，并伴随菲的形成。这些基于菲的前体为丙二烯提供了一条新的通用光化学路线，包括潜在的张力环状丙二烯。
