  The Photodecarboxylative Addition of Carboxylates to Phthalimides: Scope and Limitations

  摘要：

  Intermolecular photoinduced decarboxylative additions of a series of alkylcarboxylates to N-substituted phthalimides gave the corresponding hydroxy-plithalimidines in moderate to high yields of 39-89%. The potassium salt of 1-adamantanecarboxylic acid predominately underwent simple decarboxylation when irradiated in the presence of N-methylphthalimide. In case of phthalimides carrying suitable leaving groups within the N-side chain, decarboxylation, retro-Aldol cleavage or decarbonylation preceded the intermolecular addition step.

  electrophiles has reached remarkable levels of sophistica-tion, the intermediacy of (phenanthroline)Ni(I)-alkyl species - complexes proposed in numerous Ni-catalyzed reductive cross-coupling reactions - has been subject to speculation. Herein, we report the synthesis of such elusive (phenanthro-line)Ni(I) species and their reactivity with CO2, allowing us to address a long-standing question related to

  尽管未活化的烷基亲电试剂的催化羧化已经达到了显着的复杂程度，但（菲咯啉）Ni（I）-烷基物种的中间体 - 在许多 Ni 催化的还原交叉偶联反应中提出的配合物 - 一直受到推测。在此，我们报告了这种难以捉摸的（菲线）Ni(I) 物质的合成及其与 CO2 的反应性，使我们能够解决与金属催化羧化反应相关的长期存在的问题。
