Well... in organic chemistry I've learned that BH3
-THF could be used for hydroboration.
But somehow in last week experiment, the borane-THF is used as reducing agent for carbonyl compound and I have no idea about it as reducing agent. Could someone explain to me what is the limitation of BH3
-THF compared to lithium aluminium hydride and Sodium Borohydride?
Btw.. those BH3
-THF is generated by the reaction of BF3
etherate with NaBH4
and the reacted molecules only contain carboxylic acid and ester functional group (so it is impossible to be reduced by sodium borohydride).
The molecules to be reduced is:
