Heteroaromatic secondary alcohols react with isoprene to form products of hydrohydroxyalkylation in the presence of ruthenium(0) catalysts generated from Ru3(CO)12 and tricyclohexylphosphine, enabling direct conversion of secondary to tertiary alcohols in the absence of premetalated reagents or stoichiometric byproducts. The putative oxaruthenacycle intermediate has been isolated and characterized, and reversible metallacycle formation has been demonstrated.
在由Ru₃(CO)₁₂和三环己基膦生成的钌(0)催化剂存在下,杂芳族仲醇与异戊二烯反应形成氢羟烷基化产物,从而在没有预金属化试剂或化学计量副产物的情况下实现仲醇直接转化为叔醇。已分离并表征了假定的氧钌环中间体,并证明了金属环的可逆形成。
