摘要

The rearrangement of 2-phenylbicyclo [2.1. l] hexene (6) was more complex. The major product was shown to be l-phenylbicyclo [3.1. 0] hex-2-ene (7) by the presence of two vinyl hydrogens in the IH NMR, one appearing as a doublet and the other as a doublet of multiplets. This compound was not stable to the reaction conditions, however, and slowly rearranged to 3-phenylbicyclo-[3.1. 0] hex-2-ene (5), identified by comparison with the ...
