在含有一定量乙醇的氯仿中，通过加热Shvo络合物{[(η 5 -Ph 4 c4 CO)] 2h}-Ru 2 (CO) 4 (μ-H)（1)，定量生成了羟基环戊二烯基氯化钌（η 5 -Ph 4 c4 COH）（CO） 2 RuCl(2)）。用1或2作为催化剂，在氯仿中与碳酸钠氧化醇。仲醇和伯二醇选择性氧化分别得到酮和内酯，收率很高。
A hydroxycyclopentadienyl ruthenium chloride, (η 5 -Ph 4 C 4 COH)(CO) 2 RuCl (2), is formed quantitatively by heating the Shvo complex, {[(η 5 -Ph 4 C 4 CO)] 2 H}-Ru 2 (CO) 4 (μ-H) (1), in chloroform containing a stoichiometric amount of ethanol. Alcohols are oxidized by the use of 1 or 2 as the catalyst in chloroform with sodium carbonate. Secondary alcohols and primary diols are oxidized selectively to give ketones and lactones, respectively, in excellent yields.
