چکیده
The Front Cover shows the influence of reaction solvent on purin-2-yl Grignards with carbonyl compounds. In ether (THF), gives 8-carbinol products due to a rapid isomerisation purin-8-yl, whereas performing in dichloromethane stops and yields 2-carbinols good yields. contrast aldehydes, reactions ketones require prior complexation LaCl3.2LiCl before addition Grignard reagent.
