The mono-σ-bonded organochromium(III) complexes (A) derived from (1) rearrange internally into (B) through an acylestergrouptransposition, selected experimental conditions allowing either a good access to the unmaskedortho-hydroxybenzylketones (2) or a newroute to the 2-substituted benzo[b]furans (3).
衍生自(1)的单σ键合有机铬(III)配合物通过酰基酯基转移在内部重新排列为(B),选择的实验条件使得可以很好地接触未掩盖的邻羟基苄基酮(2)或新的途径取代2-取代的苯并[ b ]呋喃(3)。
