摘要

Abstract: A convenient, high-yield synthesis of 5H-dibenzo [a, c] cyclohepten-5-one is reported and the properties of dibenzo [a, c] cycloheptatrienylidene are examined. As previously reported2 for 4, 5-benzocycloheptatrienylidene, dibenzo [a, c] cycloheptatrienylidene rearranges rapidly in solution to an arylcarbene (9- phenanthrylcarbene). When the annelated cycloheptatrienylidenes were generated in the ...
