摘要

R= H, in cyclohexane for 3 hr. at room temperature, with a Nester-Faust NFUV-300 ultraviolet source, afforded phenanthrene (XI, R= H), in 90% yield. The progress of the reaction was followed by ultraviolet spectral analysis after appropriate time intervals. Similarly, 2-methyl-2'-iodo-cis-stilbene (X, R= CH,), photolyzed for 4 hr., afforded XI, R= CH,, in 96% yield, melting point undepressed upon admixture with an authentic sample ...
