Tricarbonyl-(3-methoxycyclohexa-2,4-dien-1-yl)-iron(1+) PF6(1-) 2 reacts with a variety of nucleophiles to give 5-substituted cyclohex-2-enones. 2 is shown to be a useful precursor for a convergent synthesis of 5-substituted cyclohex-2-enones and to be synthetically equivalent to the 5-cyclohex-2-enone cation 1.
三羰基-(3-甲氧基环己-2,4-二烯-1-基)-
铁(1+)PF 6(1-)2与多种亲核试剂反应,生成5-取代的环己-2-烯酮。图2所示为5取代的环己2-2-烯酮的聚合合成中有用的前体,并且在合成上等同于5环己2烯酮阳离子1。
