This chapter provides an overview of the survey of laboratory methods associated with the reactions of aldehydes and ketones. α-Hydroxyacetylenes, compounds with the general structure R 1 C≡CC(R 2 )(R 3 )OH, are extremely important intermediates and end products in acetylenic chemistry. They...
It also highlights applications of amidine-, isothiourea-, and guanidine-based nucleophilic catalysts for a range of reactions of carbonyl compounds. A fluorous chiral organocatalyst promotes the formation of the anti-aldol product on reaction between aromatic aldehydes with ketones in brine. The ...
Reactions of aldehydes and ketones: oxidation reduction nucleophilic addition 1) Aldehydes are easily oxidized, ketones are not. 2) Aldehydes are more reactive in nucleophilic additions than ketones. alkane alcohol aldehyde ketone carboxylic acid oxidation reduction reduction addition product nucleophilic ad...
Aldehydes and ketones undergo a variety of reactions that lead to many different products. The most common reactions are nucleophilic addition reactions, which lead to the formation of alcohols, alkenes, diols, cyanohydrins (RCH(OH)C&tbond;N), and imines R2C&dbond;NR), to mention a few repre...

Proline-catalyzed asymmetric aldol reactions between ketones and alpha-unsubstituted aldehydes [reaction: see text] With this communication we extend the methodology of proline-catalyzed direct asymmetric aldol reactions to include alpha-unsubstituted aldehydes as acceptors. This important aldehyde class giv...
(iii) The aldehydes and ketones undergo a number of addition reactions. (b) How will you distinguish between these compounds: (i) Acetaldehyde and benzaldehyde (ii) Propanone and propanol View Solution Why do aldehydes and ketones undergo nucleophilic addition reactions. Give one example. ...
