Abstract
The deoxygenation of alcohols is an important research area in modern organic chemistry that has been studied extensively. However, a chemoselective and clean method is still desirable for the emerging large scale bio-chemicals production. Herein, we report a method for alcohols deoxygenation to alkanesusing hydrogen as the reductant assisted by iodide without metal catalyst. This method is simple and green without consume quantitative extra reagents. Substrate scope study showed that this method tolerated a broad scope of functional groups including phenyl, naphthyl and allyl alcohol derivatives. Kinetics study revealed that the C-I (formed by hydroxyl group substituted by iodide) cleavage was the rate-determining step. Mechanistic study suggested a radical mechanism for this alcohol deoxygenation reactions.
期刊介绍:
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
