The reason behind the usage of dry apparatus and solvents when the borane-THF complex solution needs to be used should be given. Concept introduction: Hydroboration-oxidation involves a sequence of two reactions. The hydroboration stage involves the treatment of alkene with diborane that generates alkyl borane. In second stage hydrogen peroxide in alkaline medium is used to oxidize the alkyl borane produced in step 1 that leads to the synthesis of alcohols from alkenes . Anti-Markovnikov’s Rule serves as the basis ofhydroboration. It states that the negative part of reagent must go to the carbon that has fewer alkyl substituents or more H atoms. This rule is followed in case of hydroboration reaction or reaction with peroxides.
