13 Nov cannizzaro reaction mechanism
2 An interesting variant, the Crossed Cannizzaro Reaction, uses formaldehyde as reducing agent: At the present time, various oxidizing and reducing agents can be used to carry out such conversions (with higher yields), so that today the Cannizzaro Reaction has limited synthetic utility except for the abovementioned conversion of α-keto aldehydes. Bhojaraj, Pramod Harley, Michael Rajamathi.
