WebIt's difficult to understand because the mechanism is not completely known. But the ozonolysis of alkynes in the absence of water generally gives an anhydride: RC≡CR' + O₃ → RCO-O-COR'. If the reaction is performed in the presence of water, the anhydride hydrolyzes to form two carboxylic acids: RCO-O-OCOR' + H₂O →RCOOH + R'COOH. WebMar 24, 2024 · The hydroboration–oxidation of but-2-yne forms a single pure product because but-2-yne is a symmetrical alkyne. Pent-2-yne forms two products because it is an unsymmetrical alkyne.
