摘要

In a typical experiment, a benzene solution of TsBr (1eq.) and AIBN (0.25eq.) was slowly (1 mmol./H) added to a 0.005M refluxing benzene solution of the allylallene 1. The mixture was refluxed until the starting material disappeared on TLC plates. After evaporation of the solvent, the crude product was purified by flash chromatography over silicagel or by recrystallization. All compounds have spectral data (IR, 1 H NMR, 13 C NMR) and ...
