NaBH4 yields with varying solvents?
« on: July 18, 2003, 09:59:00 PM »
Almost everyone uses MeOH for their NaBH4, MDP2P -> MDMA reductions. Has anyone tried using EtOH or IPOH?

Just wondering if anyone had noticed any yield variation with using bulkier alcohols?

The general concensus will probably be to use MeOH, but I just want to hear from the more adventurous out there.

I don't remember asking anything about that...I want actual tried and tested yields first-hand.

Sometimes just seems to easy for some people to type UTFSE than give an intelligent response!

NaBH4 yields with varying solvents?

Are you saying that Water and Toluene are not varying solvents to Methanol?

I want actual tried and tested yields first-hand.

So, are you saying that Barium is bullshitting?

Sometimes just seems to easy for some people to type UTFSE than give an intelligent response!

Sometimes it just seems easy for some people to can others that are trying to help, rather than admit that their questions weren't properly worded.

Have a nice day

Your comments would hold some value if they weren't just based on the title for the thread. If you go on to *actually* read the question then you will see reference to only alcohols as the varying solvents.

Obviously you had nothing to contribute to the thread except misguided observations.

My question was worded quite well, but maybe the ear of wheat between your teeth and your collar rubbing on your sunburn was enough to distract you from reading it?

Any genuine responses are quite welcome, thanks.

The title of your thread happens to be succeeded by something that is commonly referred to as "A question mark".

Question marks are commonly denoted with this symbol- "?"

It's use in the written form is to imply the asking of a question.

In future when I see one of your posts, rather than attempting to assist you with my very limited knowledge, I will just reach out for another ear of wheat and put on some sunscreen. ;)
