Polare und sterische Effekte bei Oxidationsreaktionen mit aliphatischen Persäuren

Abstract

Polar and Steric Effects in Oxidation Reactions with Aliphatic Peracids Epoxidation rates of substituted peracids yield Taft reaction constants of p * = +2.0 and δ ≅ 0; the reaction order is secured and it is shown for in situ epoxidations that formation of the peracid is the slow step. α‐Halopercarboxylic acids are eletrophilic enough to oxidize paraffines selectively. Attempts to use hydrophobic interactions between ( E )‐2‐octene and steroid carboxylic acids during in situ oxidations in protic solvents for asymmetric induction did not yield optical active compounds.
