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...
A variety of aldehydes (13 examples) and ketones (11 examples) were efficiently reduced under mild conditions [Cp(CO)2Mn(IMes) (1mol%), Ph2SiH2 (1.5equiv.), h (350nm), toluene, 25掳C, 124h] with good functional group tolerance....

Suitable organic liquids include paraffins, chloroparaffins, chloro-olefines and aliphatic ethers. Suitable mercuric salts include the sulphate, organic sulphonates, acetate, haloacetates, perchlorate, oxalate, succinate and fluoborate. Examples illustrate the preparation of acrolein from propylene, methyl...
In both aldehydes and ketones, the geometry around the carbon atom in the carbonyl group is trigonal planar; the carbon atom exhibitssp2hybridization. Two of thesp2orbitals on the carbon atom in the carbonyl group are used to form σ bonds to the other carbon or hydrogen atoms in a molecule...
MCQs on Aldehydes Ketones and Carboxylic Acids: Aldehydes Ketones and Carboxylic AcidsShare Aldehydes, ketones, carboxylic acids, and their derivatives are examples of organic compounds with carbonyl groups. The carbonyl carbon in formaldehyde, the most basic aldehyde, is linked to two hydrogen atoms....
2.The straight-chain compounds were relatively more abundant than the aromatic aldehydes and the branch-chain aldehydes in the oil smoke. 油烟烟气中直链的羰基化合物的浓度大于支链及环状的羰基化合物的浓度; 3.The product was mainly consisted of acids, alcohols, aldehydes, ketones, esters, water and...
aldehydes or ketones using Ph(2)SiH(2) or PhSiH(3) has been effectively promoted by the direct use of Bu(2)SnClH-pyridine N-oxide as a catalyst; this method has advantages in terms of its mild conditions and wide application to various carbonyls and amines, including aliphatic examples.被...
Common alkylation agents, that is, alkyl halides, are notorious substrates for both Lewis acids and organocatalysts. Recently, olefins emerged as a benign alkylating species via photo/radical mechanisms. However, examples of enantioselective alkylation of aldehydes/ketones are scarce and direct ...
