通过在环境和高压(4 kbar)下对各种同位素化合物的非弹性和准弹性中子散射研究了乙酰丙酮甲基的隧穿和释放动力学。通过淬火液体制备的样品显示由分子的酮和烯醇形式的混合物组成。这一事实解释了以前研究的数据分析中的困难。在目前的工作中,可以通过制备纯烯醇样品和富含酮的样品来分离两种形式的贡献。对于烯醇形式,确定了两个不等价的甲基,其势垒高度在 220-800 K 范围内。这些势垒对非甲基质子的氘化和晶体中的无序相当敏感。相比之下,对于酮形式,电位对这些因素不敏感。这些差异反映了氢键质子对烯醇分子中甲基动力学的影响。

An Ag-catalyzed radical cascade bicyclization/aromatization of C-linked 1,7-enynes with 1,3-dicarbonyls has been achieved, providing a step- and atom-economy approach for the construction of 2,3-dihydro-1H-cyclopenta[a]naphthalenes, an important structural scaffold existed in biologically active compounds. From this transformation, structurally diverse 2,3-dihydro-1H-cyclopenta[a]naphthalenes were
