We are professional. The only reason we demand correct spelling is to avoid errors - there is only a single letter's difference between 'nitrate' and 'nitrite', for instance, yet they are two different anions that react differently. If English is not your first language, then we take this into consideration and appreciate some mistakes may be made, which we work with.

If I were you, if you want some respect around here I'd start posting properly and stop annoying myself and others - should I share some of the U2Us you've sent me?

At the moment, you appear to be borderline k3wl. Grow up, and we shall respect you and help you in any way you can, providing you pull your weight and do some work for yourself.

Back on topic, answer my question, please; what does your 'helpee' want the reagent for, and why is 42% yield not good enough? This is a single-step synthesis, which is comparatively straightforward as you asked.

Reactions where this compound is a product:
(Sn2)0
from bromomethane, 2-phenylethane-1,1-diol

from 1-bromo-2-phenyl-ethanol, methanol

from (2-bromo-2-methoxy-ethyl)benzene, water

from chloromethane, 2-phenylethane-1,1-diol

from 1-chloro-2-phenyl-ethanol, methanol




from (2-chloro-2-methoxy-ethyl)benzene, water

from fluoromethane, 2-phenylethane-1,1-diol

from iodomethane, 2-phenylethane-1,1-diol


How do I know which one gives the best yield?

As I have told you before , I don't know much in Chemistry. Keeping this in mind, If you can give me best methodology in your opinion.

You need to find actual scientific references of people who have carried out the synth. Those are just some theoretical synths.

Interesting, that is a different compound from earlier.

Do you want;

1-Methoxy-2-phenylethanol

or

(2-methoxyethyl)benzene ??

Do the synths yourself. If you cant find literature you need to do something called... experimentation!!!! The scientific method!!! Form a hypothesis, then test it. Compare results. Find the best synthesis route for this compound you are looking for. Then post it here so all will know.

Well, the reference you give and the synthesis strategies you list from it are for the other compound, thus they are not exactly what you are looking for. Back to the drawing board.

This product have a CAS number. Obviously its available in the market. There must be a complete methodology / process for preparation in some Journal or books?

Thanks, zoombafu.

Traumenz, if that's not good enough for you, then I'd consider doing some more research work yourself.

Hi

Here is the link to the reference you quoted.

http://www.tandfonline.com/doi/abs/10.1080/00397919508015447

Paying USD 43.00 for such a dear reference will not be asking much for a professional like you.
However I wonder what good that will be as cursory browsing shows the paper does not mentions your target compound.

Any updates, traumenz?

Have you or your "chemist" friend done any more work towards his synthesis?

All of this crap over a simple chemistry question?

Your product is an ether of common phenethyl alcohol. Phenethyl alcohol is often used in "Rose" type perfumes.

Unfortunately for you, most of the common methods for producing such ethers...employ fairly toxic reagents.

If you need a small amount, try e-bay...If you need a lot, and you are not chemically adept, contact a manufacturer in China.

They usually want to sell you a ton or so, but they can often be convinced to supply a "sample" amount. A kilo or so, at a friendly price.

I know this is an old thread, but I happened to stumble upon it when researching the product in question here. I thought I'd share that the essential oil of a plant called Kewda happens to have around 80% (2-methoxyethyl) benzene. You could just buy some of that E.O. and fractionate the desired component. Below is a GCMS report from an analysis I personally did.
