Let's try to predict what reagents would carry out these syntheses.
00:09
On the first one here, we want to add two bromines, and they're on the carbon that had the alkenes, or the two carbons that had the alkyne.
00:19
So this will just be br2.
00:23
For this one, we're just removing a double bond.
00:26
So this would be h2 over palladium.
00:31
For this one, we're only adding one bromine, so we can say that this is.
00:35
Was hbr.
00:37
And yes, technically, there could be a carbocadion shift to this carbon.
00:44
But both of those carbons are secondary carbon, so there is really no need or benefit in doing so.
00:54
For this one, we're changing the alken into an epoxide.
00:57
So this will be mcpba or any other r -c -o -o -o -h, any per -o -o -h, any per -o -o -h.
01:13
Or peroxycarboxylacic acid being used.
01:19
For this one, we're just cleaving, it looks like, this bond right here, and making an aldehyde...
