1,1-Dilithio-2,2-diphenylethene (14) is accessible through double bromine lithium exchange reaction starting from 1,1-dibromo-2,2-diphenylethene (5) with lithium metal at -110°C. 14 undergoes rearrangement into (E)-1-lithio-2-(2-lithiophenyl)-2-phenylethene (13) at temperatures above -100°C. The (Z)-compound 15 was formed from the (E)-compound 13 at temperatures above -25°C.
