The first example of an alkyne-substituted tricarbonyl(η5-cyclohexadienyl)iron(1+) complex has been prepared and the ω directing effect of the phenylethynyl substituent has been demonstrated in nucleophile addition reactions. Addition of NC− also occurs at the a position to form an unusual η1, η3-structure.
炔基取代的三羰基(η的第一例5 -cyclohexadienyl)
铁(1+)复合已经制备和引导所述苯基
乙炔基取代基的效果的ω已在亲核加成反应得到证实。NC的加成-也发生在一个位置,以形成一个不寻常的η 1,η 3 -结构。
