(3E)-6-Oxo-1,3-dienetricarbonyliron complexes 1 can be demetalated in good yields exclusively either to the free unrearranged (3E)-6-oxodiene 2 with ceric ammonium nitrate in methanol or to the (2Z)-6-oxoallylalcohol 3 by an excess of NaOH/H2O2.
(3E)-6-氧代-1,3-二烯三羰基铁配合物1可以在良好收率下,通过硫酸铈铵在甲醇中脱金属化,专一性地得到未重排的(3E)-6-氧代二烯2,或者通过过量的氢氧化钠/过氧化氢脱金属化得到(2Z)-6-氧代烯丙醇3。
