Beschreibungen/Notizen

• A phosphine [P(n‐Bu)3]‐catalyzed reaction for the synthesis of phosphono‐chromans from allenylphosphonates and salicyl N‐thiophosphinyl imines has been described and compared with reactions for phosphorus‐free allenes. The products are (β,γ)‐cyclized and are obtained in good yields (57–83%). A key product is characterized by X‐ray crystallography.
