electrophiile reactivity in the presence of NaBH4
« on: October 25, 2009, 12:33:10 AM »
If i was to rank the following from the most to the least reactive in the presence of NaBH4 i would say that the aldehyde > ketone> ester . I'm not sure what to make out of the diketone...where would it fit in?

Think about your reason for ranking the other three as you did.  What is the deciding factor?  Now think about the diketone – how does a withdrawing group adjacent to the reactive center fit into your reasoning?

Firstly i think the  diliketone is more active than the ketone,but the aldehide is also the most active group in it.The ester group can't react with the NaBH4
