TL;DR: Aliphatic and alicyclic gem-bis-hydroperoxides and their derivatives, bis(1-hydric peroxides), dispiro-and tetraalkyl-1,2,4,5-tetroxanes were synthesized by the reaction of aliphatic alicycic acetals and enol ethers with H2O2 in the presence of BF3 in anhydrous Et2O.

TL;DR: In this article, the use of Pb(OAc)4 as an oxidizer in the decarboxylation of carboxylic acids with lead tetraacetate has been studied in detail.
Abstract: Oxidative decarboxylation of carboxylic acids with lead tetraacetate has been studied in detail. Numerous repre� sentatives of aliphatic, alicyclic, and arylaliphatic acids were examined in this reaction. 2 The use of Pb(OAc) 4 and the Pb(OAc) 4 —I, Pb(OAc) 4 —Cu(OAc) 2 , and Pb(OAc)4—MHal oxidizing systems (M is alkali metal) opens new ways of transforming acids into unsaturated hydrocarbons and halohydrocarbons. Oxidative decar� boxylation was carried out in a liquid phase generally at high temperature with the use of solvents (benzene, dichloromethane, acetic acid, etc.). We were the first to use Pb(OAc)4 as an oxidizer in the
