Pyrolysis of the cis title compound gives over 99% trans-stilbene in various solvents at 33°–91°, while at higher temperatures 2,2-diphenylethanal hydrazone is produced: at 33°–175° the trans title compound gives 83–100% trans-stilbene.
在33°–91°C的各种溶剂中,顺式标题化合物的热解可产生99%以上的反式-
二苯乙烯;而在更高的温度下,则可生成2,2-二苯基乙33:在33°-175°时,反式标题化合物可得到83–100 %反式
二苯乙烯。
