Özet
İngilizce (OpenAlex)
Abstract Acetate derivatives of 2‐en‐4‐yne alcohols 1 and enyne oxiranes 4 regioselectively underwent 1,5‐substitution (SN2′′) reactions with Grignard reagents in the presence of an iron compound to provide vinylallenes exclusively with the (E)‐configuration. An alkali salt was needed to avoid the hydride‐promoted reductive 1,5‐substitution pathway for 1, whereas no such additive was needed for the effective conversion of 4 into the desired alkylated or arylated vinylallene structure.
