The photochemical exchange of all three carbonyl ligands with acetonitrile converts tricarbonyliron-diene complexes into the very labile triacetonitrile-iron-diene complexes. These easily demetalate in high yields to the corresponding free ligands on injection of air at -30°C [Eq. (1)]. The novel demetalation procedure is applied to the tricarbonyliron complexes of cyclopentadienones, cyclohexa-1,3-dienes
所有三个羰基配体与乙腈的光化学交换将三羰基铁-二烯配合物转化为非常不稳定的三乙腈-铁-二烯配合物。在-30°C注入空气时,这些金属很容易以高收率脱金属成相应的游离配体。(1)]。该新颖的脱金属方法适用于环戊二烯酮,环己-1,3-二烯和buta-1,3-二烯的三羰基铁配合物。
