WebJul 10, 2024 · The use of triphenylphosphine, thiourea, zinc dust, or dimethyl sulfide produces aldehydes or ketones while the use of sodium borohydride produces alcohols. The use of hydrogen peroxide produces carboxylic acids. ... whereas reductive ozonolysis gives either alcohols or carbonyl compounds. Ozonolysis is an organic chemical reaction where ... WebOzonolysis of Alkynes Mechanism The alkyne reacts with the ozone, causing the breakage of the alkyne. This gives rise to the ozonide intermediate. A simple aqueous workup follows with the help of zinc metal, finally yielding a dicarbonyl compound. The reaction can be written as: Ozonolysis of Elastomers – Ozone Cracking
