00:01
Here the reaction is in between ethyl malonate which is double bond o, double bond o, o ethyl.
00:12
Here o ethyl group, this is our ethyl malonate and it reacts with salicyllideide.
00:24
Solicilide is 1 -cho group, aldehyde group and 1 -oh.
00:31
This is our salicyllide dehydehyde.
00:39
Hence we will find out the product as when it reacts to piperedin in presence of vein jol and heated, the product will be here the presence of o h group and from these there will be attachment of the malonate group that is double 1o, double 1 o o ethyl.
01:16
So let's see what is the reaction mechanism for thus this reaction.
01:22
The mechanism will be if you take the papyridine, pipidine having the lone paraprofen on nitrogen reacts with ethyl malonate which is p .o2 ethyl here to h2 present.
01:49
What will happen? this lumper of a electron will attract this hydrogen and this bond will go to the carbon atom.
01:58
Hence we will get here at this carbon atom there is a negative chap and here co2 ethyl and co2 ethyl.
02:12
Here this is the intermediate form which is an inlet.
02:20
Now to this compound or to this intermediate, we are a intermediate...
