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
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

Three of the substrates had a second halogen on the bposition in the molecule. This work also compared the behavior of two nucleophiles:dianion I and II. You should read the abstract and look at Scheme 1 (p. 3082) and Table 4(p. 3086). Abstract: The gas-phase reactions of benzoate and phenolate containing dianions with a series of ‚-substitutedalkyl bromides (X-CH2CH2Br, X ) H, F, Cl, Br) have been studied in a quadrupole ion trap mass spectrometer.Branching ratios between SN 2 and E2 products were measured and rate constants were determined. The‚-halogens increase both the S N 2 and E2 rates, but the effect is greater for the latter process and thereforethese substituents lead to an increase in the amount of elimination. The kinetic data for the SN 2 reactions canbe analyzed via a two-parameter, linear free-energy relationship and the results indicate that field-effects (i.e.,electron-withdrawing…arrow_forward
