摘要：

The synthesis of tertiary alcohol via chelation-assisted nickel-catalyzed addition of arylboronic acids to unactivated ketones was reported in this study. A series of substituted arylboronic acids was reacted with 1-(quinolin-8-yl)ethan-1-one and its derivatives to provide various substituted 1-aryl-1-(quinolin-8-yl)ethan-1-ols and relevant compounds in medium to good yields. The N-directing group is essential for the addition reaction of arylboronic acids to these unactivated ketones. Nickel(II) acetylacetonate (10.0 mol%) in combination with sodium iodide (2 equiv.) and potassium carbonate (0.8 equiv.) was identified as the optimal catalytic system for the current transformations.
