摘要

在这项工作中，成功制备了苯酚和醇的硅基醚，并将其作为以碳（硅）为中心的中性自由基前体进行了测试。通过 Fukuzumi 催化剂对这些醚进行有机光催化氧化，导致 C-Si（或 Si-Si）键断裂，从而释放出所需自由基，并通过 Giese 反应锻造出 C（sp3）-C（sp3）（或 C（sp3）-Si）键。

Organophotocatalyzed C−Si Bond Fragmentation Using Silyl Ethers as Radical Precursors

In this work, silyl ethers of phenols and alcohols have been successfully prepared and tested as neutral carbon (silicon) centered radical precursors. The organophotocatalyzed oxidation (by the Fukuzumi catalyst) of these ethers caused the cleavage of a C−Si (or a Si−Si) bond for the release of the desired radical to be used for the forging of C(sp³) −C(sp³) (or C(sp³) −Si) bonds via a Giese reaction.

期刊介绍： Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry. The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
