| Abstract: | The paper reports the reductive coupling of aromatic ketones to alkanes by low-valent titanium salt. The low-valent titanuim salt, produced by re- duction of titanium tetrachloride with zinc, reacts with aromatic ketones in refluxing tetraliydrofuran to give the coupled alkanes in good yields. The intramolecular reductive coupling of highly sterically congested diketone to the corresponding cycloalkane can also be carries out in this reaction. |
