摘要： A efficient photochemical method for the preparation of an alcohol compound, e.g., benzyl alcohol, from a non-olefin hydrocarbon compound, e.g., benzene, was proposed in which a mixture of the non-olefin hydrocarbon compound as the starting material and a hydrogen donor compound, which is a cycloalkane of 5 to 16 carbon atoms in a molecule, e.g., cyclooctane, or an aliphatic alcohol of up to 10 carbon atoms in a molecule, e.g., isopropyl alcohol, is irradiated with light under an atmosphere of carbon monoxide in the presence of a complex compound of rhodium or iridium, of which at least one of the ligands is preferably a monophosphine or bisphosphine compound. The method is advantageous in that the reaction can proceed under mild reaction conditions and that the amount of the aldehyde compound formed in the reaction mixture as a by-product is very small as compared with conventional methods so as to greatly facilitate isolation of the desired alcohol product from the reaction mixture.
摘要翻译：提出了一种用于制备来自非烯烃烃化合物例如苯的醇化合物（例如苄醇）的有效光化学方法，其中以非烯烃烃化合物作为原料的混合物和氢供体化合物，其是分子中具有5至16个碳原子的环烷烃，例如环辛烷或分子中具有至多10个碳原子的脂族醇，例如异丙醇，在一氧化碳气氛下用光照射存在铑或铱的复合化合物，其中至少一种配体优选为单膦或双膦化合物。该方法的优点在于反应可以在温和的反应条件下进行，并且与常规方法相比，作为副产物的反应混合物中形成的醛化合物的量非常小，以便极大地促进所需醇的分离反应混合物中的产物。
