在我们实验室里采用环戊二烯基羰基铁的钠盐[(η~5-C_5H_5)Fe(CO)_2]Na和氯代乙酸酯ClCH_2COOR(R=C_2H_5,C_3H_7,C_4H_9,C_5H_(11))直接反应合成了铁羰基化合物(η~5-C_5H_5)Fe(CO)_2CH_2COOR(Ⅰ).并通过IR、~1H NMR、~(13)C NMR以及MS的分析,确定了(Ⅰ)的结构.η~5-环戊二烯基(2-烷氧基-2-氧代乙基)二羰基合铁(Ⅰ)的合成路线如下:
In our laboratory, we used the sodium salt of cyclopentadienyl iron carbonyl [(η5-C_5H_5) Fe (CO) _2] Na and the chloroacetate ClCH_2COOR (R = C_2H_5, C_3H_7, C_4H_9, C_5H_ ) (Fe (CO) _2CH_2COOR (Ⅰ)) was synthesized by the direct reaction of Fe (CO) _2CH_2COOR (Ⅰ) with IR, ~ 1H NMR and ~ (13) C NMR and MS, The structure of η ~ 5-cyclopentadienyl (2-alkoxy-2-oxoethyl) dicarbonyl iron (Ⅰ) is as follows:
