Okay, so we want to get the products and the following reactions with these alkenes.
00:08
So we have the structure.
00:12
We have a hydroboration reaction.
00:14
So this involves borane.
00:17
And this is with some ether, ether, so thhf is an example.
00:25
So we draw the structure of borne.
00:30
The hydra is actually more electrone negative than boron.
00:34
It's got a partial negative charge.
00:35
And boron has to have a partial positive charge.
00:37
So as a result, the alkenes attack boron while the hydrogen attacks the more substitute carbon.
00:47
So you're going to get this structure.
00:57
This is eventually going to break down because it's very unstable.
01:01
So you have the hydrogen here and the addition of bh2 right here.
01:05
At the same time, sodium hydroxide is going to react with peroxide.
01:15
The oh is going to depertinate peroxide, and we'll get the conjugate base.
01:24
Let's get attack boron.
01:26
As a result, it's going to have a negative charge.
01:36
So this is the organoboro intermediate in the reaction.
01:42
Is peroxide.
01:52
This is going to transfer a pair of electrons because oxygen's more electrone -negative than boron, and it can stabilize the negative charge better.
02:00
This group's going to leave as a result, the o -h.
02:03
So now we have the structure.
02:11
We have we're going to switch the oxygen in the and boron.
02:24
So this is going to be depredinated by hydroxide that was expelled.
02:30
It's going to leave.
02:32
And we'll get the alcoxide ion.
02:39
It's not water is going to form from hydrogen...
