Bisphosphorylallenes were easily obtained in multigram scale from the Wittig-type rearrangement of bispropargyl alcohols. Unlike other conjugated bis-allenes, these reagents underwent a double cyclization mediated by iodine or copper dibromide leading to the formation of bis-1,2-oxaphospholenes.
双膦酰基烯丙基化合物可以通过双炔丙基醇的 Wittig 型重排反应以多克级规模轻松获得。与其他共轭双烯丙基化合物不同，这些试剂通过碘或二溴化铜介导的双重环化反应，形成双-1,2-氧杂磷杂环戊烯。
