Ignoring stereochemistry, draw the alkylborane formed from the addition of one equivalent of BH3 to the alkene.
The alkylborane formed in Part 1 is further treated with H2O2 and HO−. Draw the two stereoisomers of the final product of the reaction. Include stereochemistry where relevant.
How many stereocenters are formed from the reaction?
What is the relationship between the stereoisomers?
why do (R)-3-chloro-1-methylcycloprop-1-ene and 5-Bromo-1,3-Cyclohexadiene react differently with cyanide (why doesn't cyanide pass through its usual mechanism for these two products and what did you obtain these specific products)
Account for the regioselectivity and stereoselectivity observed when 1-methylcyclopentene is treated with reagent.
Q) Br2 in H2O
