Free-radical addition of hydrogen bromide to 1 gave an 80% yield of 7-bromodispiro[2.0.2.2]octane 2a. At 10掳, hydroboration-oxidation of 1 was found to give mainly 7-hydroxydispiro[2.0.2.2]octane 2a in ca. 90% yield; at 25掳, near equal amounts of 2c and 4-(2-hydroxyethyl) ...

Another violation of the Markovnikov rule occurs in reactions involving the addition of HBr to olefins in the presence of peroxides (the Kharasch effect), since the reaction mechanism here is radical. Atomic bromine is the attacking particle, and the orientation of the addition is determined by th...
To determine the most stable free radical among the given options, we will analyze each free radical based on resonance and hyperconjugation effects.Step 1: Analyze the first free radical (Allyl free radical) The first free rad
The addition of tert-butanol (TBA) acting as a hydroxyl radical (∙OH) scavenger had little effect on the photocatalytic activity, suggesting that ∙OH radicals rarely involve in the photocatalytic reaction. However, both electron (e−) scavenger (K2S2O8) and ∙O2− scavenger (1,4-...
