説明
<jats:title>Abstract</jats:title><jats:p>4‐Chloropyridine can be converted for about 70% into a complex magnesium compound, which reacts in the manner of a <jats:italic>Grignard</jats:italic> compound with aldehydes or ketones, forming (4‐pyridyl)‐carbinols; with orthoformic ester, (4‐pyridyl)‐methanal‐acetal is formed.</jats:p><jats:p>The reaction of 4‐lithiopyridine with benzophenone and with ethyl benzoate respectively leads to the formation of (4‐pyridyl)‐diphenyl‐carbinol and to bis‐(4‐pyridyl)‐phenyl‐carbinol respectively. With aromatic nitriles, (4‐pyridyl)‐aryl ketones are formed.</jats:p><jats:p>The reactions of 4‐lithiopyridine with cyanopyridines or with pyridine‐carboxylic esters lead to the formation of bis‐pyridyl ketones, <jats:italic>e.g.</jats:italic>, bis‐(4‐pyridyl) ketone.</jats:p><jats:p>Quinolyl ketones are obtained by starting from 3‐lithioquinoline.</jats:p>
