One-pot reaction of allyl halides with [Bu4N]+[Fe(CO)3(NO)]- followed by treatment with 1,2-bis(diphenylphosphino)ethane gave βγ-unsaturated acyl iron complexes in good yields via regioselective carbonylation with retention of configuration of the allylic double bond. β,γ-Unsaturated carboxylic acid esters and amides were prepared upon treatment of the acyl iron complexes with alcohols and amines in the presence of iodine.
一步反应法将烯丙基卤与[Bu4N]+[Fe(CO)3(NO)]-反应,随后用1,2-双(二苯膺)乙烷处理,通过区域选择性羰基化并保持烯丙基双键构型,以良好产率得到βγ-不饱和酰基铁配合物。在碘的存在下,将这些酰基铁配合物与醇和胺反应,制备了β,γ-不饱和羧酸酯和酰胺。
