光化学反应节能、洁净、节约的特点为发展原子经济、步骤经济的绿色环保合成化学注入了活力.我们借助可见光催化反应发展了一类新反应——可见光催化交叉偶联放氢反应.该反应不需要额外氧化剂的参与,直接实现两种不同碳氢键(或碳氢键和杂氢键)的直接偶联,生成新的碳碳键(或碳杂键和杂杂键)同时,氢气为唯一的副产物.相比于传统的合成方法,该策略在温和的反应条件下,避免了氧化剂的使用,减少了副反应的发生,近几年已被应用于多种化学键的构建.简要讨论可见光催化交叉偶联放氢反应的发展及其在有机合成领域的应用,期望能够更全面地理解这种新型催化模式,为开发绿色高效、步骤经济以及原子经济的合成策略和实际应用提供参考.
Photochemical Reactions The energy-saving, clean and economical features have injected vitality into the development of atomic economy and step-by-step green synthesis chemistry. We developed a new class of reaction-visible light photocatalytic cross-coupling desorption reaction with visible light catalytic reaction. Additional oxidants are required to directly couple two different carbon-hydrogen bonds (or hydrocarbon- and hetero-hydrogen bonds) to create new carbon-carbon bonds (or carbon and miscellaneous bonds) while hydrogen is unique Compared with the traditional synthesis method, the strategy under mild reaction conditions, to avoid the use of oxidants to reduce the incidence of side effects, in recent years has been applied to a variety of chemical bonds in the construction of a brief discussion of visible light Catalytic cross-coupling hydrogen evolution reaction and its application in the field of organic synthesis, expect to be able to more fully understand this new catalytic model for the development of green and efficient, step-by-step economy and atomic economy of synthetic strategies and practical reference.
