  Ligand-Accelerated Iron Photocatalysis Enabling Decarboxylative Alkylation of Heteroarenes

  摘要：

  A mild, practical protocol for the decarboxylative alkylation of heteroarenes has been accomplished via iron photocatalysis. A diverse range of carboxylic acids readily undergo oxidative decarboxylation and then couple with a broad array of heteroarenes in this transformation. The photoexcited state lifetimes of iron complexes are typically much shorter than those of iridium and ruthenium complexes. Here we describe our effort on iron photocatalysis by utilizing the intramolecular charge transfer pathway of iron-carboxylate complexes.

  Abstract A practical approach was developed for the synthesis of 4-arylquinazoline compounds through a one-pot nucleophilic arylation/alkylation of 2-chloroquinazoline with aryl lithium compounds generated in situ, followed by ring oxidation. The obtained 2-chloro-4-arylquinazoline adducts were further used as versatile intermediates that undergo a variety of synthetic transformations to provide functionalized
