Organic oxoammonium salts. 3. A new convenient method for the oxidation of alcohols to aldehydes and ketones
摘要:
A new method for the selective oxidation of alcohols using organic oxoammonium salts generated by acid-promoted disproportionation of nitroxides in solution has been developed. Major advantages are high yields, ease of product isolation, and a high degree of selectivity in the presence of other functional groups.

class of compounds. Nonetheless, the preparation of unsymmetrical 1,2-diols via the direct cross-coupling of two different carbonylcompoundsundersimple and mild conditions remains an elusive goal. Herein, an operationally simple electroreductive cross-coupling of two common carbonyls, aldehydes and ketones using electrons as safe reducing agents is reported. By applying this new protocol, a library
