Abstract
The reaction of aldehydes with trichloromethide followed by reductive ring opening under basic conditions affords homologated carboxylic acids in high yields. This operationally simple procedure provides a practical, efficient alternative to other homologation protocols and is compatible with sensitive aldehydes including enals and enolizable substrates.
