16. We examined separately the reaction of s-BuLi with 1-{4-[3-(4-vinylphenyl)propyl]phenyl}-1-phenylethylene, a DPE derivative substituted with a styryl group, in THF at -78°C for 30 min. Unlike the reaction of s-BuLi with 1, insoluble polymeric material and a small amount of soluble polymer with a very broad molecular distribution were obtained in the reaction. This clearly indicates that undesirable side reactions such as polymerization and/or addition reactions of both the styryl and 1,1-diphenylethenyl groups occur simultaneously. Accordingly, the anionic functionalization reaction using the DPE substituted with a styryl group was unsuccessful under the conditions employed here.
