WebMar 9, 2005 · I have got some problems on reducing agents, can someone explain why: 1) LiAlH4 and NaBH4 both reduce carboxylic acids / ketones, but only LiAlH4 reduces a nitro group? Why doesn't NaBH4 reduce the Nitro group? 2) How come H2/Nickel reduces C=C bond but LiAlH4 doesnt? 3) Similarly, why doesn't H2 reduce a carboxylic acid / … WebI guess, that combined process is also likely to work. N a B H X 4 will only reduce the R C H = C H N O X 2 to R C H X 2 C H N O X 2. An additional reducing agent, such as Z n / H C l, can reduce the nitro group to the amine. A catalyst + N a B H X 4 could do the whole thing, but you'll have to look at the literature.

The combination of B 2 pin 2 and KO t Bu enables a chemoselective, metal-free reduction of aromatic nitro compounds to the corresponding amines in very good yields in isopropanol. The reaction tolerates various reducible functional groups. WebNov 18, 2013 · I have been going through reduction of aldehydes using $\ce{LiAlH4}$ and $\ce{NaBH4}$. If there is a double bond conjugated with the carbonyl group, $\ce{LiAlH4}$ doesn't reduce it, leading to an allylic alcohol. However, using $\ce{NaBH4}$, some of the fully reduced alcohol will also be formed. Why is this so?

WebSep 23, 2015 · A rapid and efficient single-step synthesis of substituted anilines has been developed.
