Hydroboration–oxidation is an anti-Markovnikov reaction, with the hydroxyl group attaching to the less-substituted carbon. The reaction thus provides a more stereospecific and complementary regiochemical alternative to other hydration reactions such as acid-catalyzed addition and the oxymercuration–reduction process.
Methylcyclopentane is an organic compound with the chemical formula CH 3 C 5 H 9.It is a colourless, flammable liquid with a faint odor. It is a component of the naphthene fraction of petroleum usually obtained as a mixture with cyclohexane.
Catalyzed hydroboration-oxidation of substituted alkenes can be rendered enantioselective. In 1990, Brown and co-workers achieved asymmetric hydroboration using an achiral catalyst and chiral borane sources derived from ephedrine and pseudoephedrine. In most cases, the regioselectivity was poor although the ee values can be close to 90%. [16]
Cyclopentene was first prepared by Carl Gärtner in 1893 from iodocyclopentane with potassium hydroxide.He named it pentamethenylene (German: Pentamethenylen). [3] ...

Wilkinson's catalyst also catalyzes many other hydrofunctionalization reactions including hydroacylation, hydroboration, and hydrosilylation of alkenes. [14] Hydroborations have been studied with catecholborane and pinacolborane. [15] It is also active for the hydrosilylation of alkenes. [16]
Hydroboration occurs stereospecifically syn — on the same alkene face. The transition state for this concerted reaction can be visualized as a square with the corners occupied by carbon, carbon, hydrogen and boron, maximizing overlap between the olefin p-orbitals and the empty boron orbital.
A cat’s sense of smell is over three hundred times more sensitive than a human’s, and they explore their world through scent. They smell something interesting and they are curious about ...
