phenols with 1,1-diarylprop-2-yn-1-ols give indeno[2,1-i]- and indeno[1,2-f]- naphtho[2,1-b]pyranones respectively. The photochromic properties of these and the reduced derivatives are reported. A rationale for the pronounced hypsochromic shift in λmax of the photomerocyanine from a 2H,9H-indeno[1,2-f]naphtho[2,1-b]pyran is presented.
摘要 描述了通过 Suzuki-Miyaura 偶联获得的 11H-苯并 [a] 芴-11-one 的 3-羟基-和 6-羟基-衍生物的便利合成。这些酚与 1,1-二芳基丙-2-yn-1-醇的反应分别得到茚并[2,1-i]-和茚并[1,2-f]-萘并[2,1-b]吡喃酮。报道了这些和还原衍生物的光致变色特性。提出了来自 2H,9H-茚并 [1,2-f] 萘并 [2,1-b] 吡喃的光部花青的 λmax 显着减色偏移的基本原理。
