Hydration reaction of alkene is catalyzed by dilute acid. Selection of acid is important . Conjugate base of the acid should not interfere in the reaction. There are other means by which alkenes can be converted to alcohols. Oxymercuration demercuration gives Markovnikoff's alcohols while hydrobor...

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,...
PROCESS FOR THE HYDROBORATION OF ALKENES AND ALKYNESnot available for EP0212708 of corresponding document: US4731463 In a process for hydroboronizing alkenes or alkynes with catecholborane (1,3,2-benzodioxaborolane) optionally in the presence of an added organic solvent the reaction is catalyzed by...
Here we describe a copper-catalysed enantioselective hydroboration of alkenes with 1,2-benzazaborines. The method provides a general platform for the atom-economic and efficient construction of diverse chiral 1,2-benzazaborine compounds (more than 60 examples) that bear a 2-carbon-stereogenic centre...
Alkenes: Hydroboration‐Oxidation Water can be added to an alkene in such a way that the major product is not that predicted by the Markovnikov rule. An example of such a reaction is the indirect addition of water to an alkene via ahydroboration‐oxidation reaction.In this reaction, a disubst...
