Stereochemistry of hydroboration

The regioselectivity and syn stereochemistry of hydroboration-oxidation coupled with a knowledge of the chemical properties of alkenes and boranes contribute to our under standing of the reaction mechanism... [Pg.252]

Problem 15.10 The stereochemistry of hydroboration-oxidation is the net result of the stereochemistry of the two steps, and is consistent with either of two combinations of stereochemistry for the individual steps. What aic these two combinations ... [Pg.507]

The reaction in equation 9.52 does not provide a convincing demonstration of the stereochemistry of hydroboration-oxidation, since 52 is thermodynamically more stable than the corresponding cis isomer. Therefore, Brown and Zweifel also carried out the procedure on 1,2-dimethylcyclopentene (53, equation 9.53). The product of that reaction was the less stable stereoisomer... [Pg.601]

In the following sections we shall consider details of the mechanism that lead to the anti-Markovnikov regiochemistry and syn stereochemistry of hydroboration-oxidation. [Pg.352]

The overall stereochemistry of hydroboration—protonolysis, therefore, is syn (hke that of the oxidation of alkylboranes). [Pg.359]
