Addition of 2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPO) to MCl(3) (M = Fe, Al) results in the formation of MCl(3)(η(1)-TEMPO) [M = Fe (1), Al (2)]. Both 1 and 2 oxidize alcohols to generate ketones or aldehydes along with the reduced complexes MCl(3)(η(1)-TEMPOH) [M = Fe (3), Al (4)]. Complexes 1-4 were fully characterized, including analysis by X-ray crystallography. Additionally, control experiments indicated that neither MCl(3) (M = Al, Fe) nor TEMPO are capable of effecting the oxidation of alcohols independently.
2,2,6,6-四甲基哌啶-N-氧自由基（TEMPO）添加到 MCl(3)（M = Fe、Al）中会形成 MCl(3)(η(1)-TEMPO）[M = Fe（1），Al（2）]。1 和 2 均会将醇氧化为酮或醛，同时生成还原的配合物 MCl(3)(η(1)-TEMPOH）[M = Fe（3），Al（4）]。配合物 1-4 经过了充分的表征，包括 X 射线晶体学分析。此外，对照实验表明，MCl(3)（M = Al、Fe）和 TEMPO 都不能独立地实现醇的氧化。
