This is one of the reactions in the roadmap. Its thelast roadmap. What is firstly the name of this reaction, what are the possible products with it. eg from the roadmap.
CH3C=OCl goes thru (C2H5) Cu Li/Hexane gives CH3C=O-C2H5 then goes thru I2OH gives CHI3+ C2H5-C=O-O-

also is this SN1

The first reaction is the organometallic reaction known as a gillmans reagent and it substitutes a alkyl group for a halogen. Although i am not sure that it works with an oxygen, i have only seen it on a halogen attached to a carbon. Furthermore i have never seen it used on a vinyl carbon. I dunno about this. The second reaction i've never seen before. I have to look that one up.

The first reaction is neither SN1 or any type.
The second, I have never seen, and I think it is a typo or you wrote it wrong.

 

[klutzy1987]

The first reaction can not be an SN1 or SN2 reaction because they dont occur on a vinyk or aryl carbon. I am not sure where you saw this.

it is in the destroyer, i have the 2007 version, roadmap # 4, the last reaction , the last product is CHI3+ C2H5-C=O and a Oxgen with a negative attached to the carbon, so it like a COOH but oxygen iwth a charge.. does that make more sense? maybe/?

CHI3 is a haloform but i dont see a methyl ketone for that to work on.

Can someone tell me what CHI3 is and what it does?
This seems very irrelevant to to the DAT since no one has seen it.

The first reaction is a "nucleophilic addition, followed by elimination".
The second reaction is the halogenation of the CH3 group to CI3, which is then followed by the haloform reaction, where CI3 leaves by "nucleaophilic addition, elemination" again.

 

[klutzy1987]

I just said it is a haloform reaction, and it makes a methyl ketonje into a carboxylic acid.

It's not a typo bro.

second one is not completely true since it will compete with the other alpha carbon. Haloforms are usually for only methyl ketones where the alpha carbon is only on the methyl C.

I think the second one is sort of biased. Anyone agree?
