A new general anionic functionalization methodology is described based on (a) the quantitative silyl hydride functionalization of well‐defined polymeric organolithium compounds with either dimethylchlorosilane (ω‐chain end functionalization) or dichloromethylsilane (in‐chain functionalization) and (b) reaction of the silyl hydride‐functionalized polymer with a functionalized alkene using Karstedt's Pt(0) hydrosilylation catalyst.
