Reaction of benzaldehyde with acetophenone
WebThe reaction is fast at room temperature in benzene solution with 1% equivalent of catalyst, especially when involving the first hydrogen of dihydrosilanes, R 2 SiH 2. Optical yields strongly depend on the nature of this silane. Enantioselectivity can be as high as 58% in … Webcondensation reaction. Thus at higher temperature in base the aldol reaction will go directly to the conjugated enone without any isolation of the aldol intermediate. The aldehyde and ketone used for aldol reaction will be selected from the following group: CHO. CHO. …
