WebOH. This reaction mechanism is why a small amount of ozone is essential in the troposphere. Other sources of OH are: the photolysis of nitrous acid (HONO), hydrogen peroxide (H 2O 2) or peroxy-methane (CH 3OOH) the reaction of nitrogen monoxide (NO) with the hydroperoxy radical (HO 2) or the reaction of alkenes with ozone. The scheme on … WebOzonolysis allows the cleavage of alkene double bonds by reaction with ozone. Depending on the work up, different products may be isolated: reductive work-up gives either alcohols or carbonyl compounds, while oxidative work-up leads to carboxylic acids or ketones. … rcn and communicationWebAlcohols can be oxidized to aldehydes/ketones using PCC or Swern oxidation Pyridinium Chlorochromate (PCC) Pyridinium chlorochromate ( PCC) is a milder version of chromic acid. PCC oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. rcn asterix

"WebAldehydes 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 R 2 C&dbond;NR), to mention a few representative examples.
