A series of β-ferrocenecarboxyl α-diazocarbonyl compounds were prepared by the reaction of ferrocenoyl chloride with β-hydroxyl α-diazocarbonyl compounds in the presence of pyridine. The diazo decomposition of these ferrocene-containing diazocarbonyl compounds with Rh2(OAc)4 resulted in 2,3-ferrocenecarboxyl migration to give ferrocene-containing α,β-unsaturated esters in high yields.
一系列β-铁烯酰羧酸α-重氮碳酰基化合物通过铁烯酰氯与β-羟基α-重氮碳酰基化合物在吡啶存在下反应制备而成。这些含铁烯的重氮碳酰基化合物与Rh2(OAc)4发生重氮分解,导致2,3-铁烯酰迁移,从而高产率地得到含铁烯的α,β-不饱和酯。
