In the hydroboration-oxidation reaction of Propene with diborane,H2O2andNaOH, the organic compound formed is View Solution The reaction (C ) to (H) is called hydroboration oxidation of alkene. Which statement is true about the reaction ?
Hydroboration of unsaturated compounds such like alkenes or alkynes is one of the most powerful and straightforward methodology to access various organoboranes which have found widespread application in oxidation, amination and coupling reaction.1 Compared with hydroboration of non-polarized multiple bonds,...

The I2/NaBH4 system is useful in the hydrocarboration of olefins and the corresponding alcohols are obtained in 78–92% yields after H2O2/OH- oxidation. The reagent system is also useful for the reduction of carboxylic esters and acids to the corresponding alcohols in 60-90% yields. 关键词...
1.Malonyloxyborohydride,ahydroborationreagent,is prepared by reaction of malonic acid and sodium borohydride,and is used to react with dihydromyrcene in THF.用一种硼氢化试剂———丙二酸与硼氢化钠反应生成的丙二酰氧基硼氢化钠在THF中与二氢月桂烯反应制备香茅醇。
-Alkenes can be converted into anti-Markovnikov alcohols by the Brown hydroboration, which involves regio/stereoselective syn-addition of a B-H bond to the olefin followed by H2O2/NaOH oxidation. The reaction provides a complementary method to oxymercuration and hydration, which give only Markovnikov...
The reaction conditions and results are summarized in Table IV. The hydroxylated polymers obtained by oxidation after the hydro- boration of polybutadiene were not optically active. The results agree with the authors' expectation that the asymmetric carbon atoms induced in the polymer obtained by ...
