摘要

报道了伯醇的正式脱氧硅基化反应。一锅法包括醇的原位溴化和随后的镍催化形成的烷基溴和各种乙烯基取代的氯硅烷的交叉亲电偶联。成功的关键是镍催化剂以及氯硅烷亲电试剂与前面溴化步骤的副产物的相容性，特别是与三苯基氧化膦可能作为过量镍催化剂的弱配体使用。

One-Pot Sequential Alcohol Activation and Nickel-Catalyzed Cross-Electrophile Coupling with Chlorosilanes

A formal deoxygenative silylation of primary alcohols is reported. The one-pot procedure consists of an in situ bromination of the alcohol and a subsequent nickel-catalyzed cross-electrophile coupling of the formed alkyl bromide and various vinyl-substituted chlorosilanes. The key to success is the compatibility of the nickel catalysis as well as the chlorosilane electrophile with the byproducts of the preceding bromination step, especially with triphenylphosphine oxide likely acting as a weak ligand for the excess nickel catalyst used.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
