Use of Antimony trifluoride in Swarts reaction!
ProtonsTalk ^ | James

Posted on 03/16/2021 2:37:08 AM PDT by jackplanck

Hey guys,

I am currently studying organic chemistry specifically swarts reaction. I just wanted to know why do we use only Antinomy trifluoride or swarts reagent in the swarts reaction.

I tried searching but couldn't find a good explanation. It is not even mentioned in most of the articles like the article I have linked.

It would help me a lot if someone can help me out

AsF3 is less effective.

BiF3 doesn’t do it.

I'll ask my bowling team in the bar Friday night and get back with you.....

“It would help me a lot if someone can help me out.”

Sorry to be short, but shouldn’t you be (1) asking your professor? (2) going to the science library, and/or (3) exhausting on-line research?

What was the reason you chose FR for your chemistry question? How do we know this isn’t a homework assignment and you want someone to give you the answer?

Just asking.

1] My wild guess is because it works.

2] There is a place at the end of your article to leave a comment/ask a question. I’d try there.

“What was the reason you chose FR for your chemistry question?”

Because he’s indian.

When I was in school, the professors loved explaining how well the Indians did in assignments and tests. They would note that not only did the indians do very well, they all did identically well! Their modus operandi was do get together, and divide up the assignment, each going out and getting the answers from unsuspecting students or other sources. They would then share with each other.

The profs similarly warned the actual studious students that the chinese would ask you for help, and in return would give you misleading, incorrect information, thus improving their class ranking. Sort of two birds with one stone.

The blacks would just fail the course, then have their grades boosted to average, with the profs knowing that they would drop out anyway.

This was Temple U in Philadelphia.

No good. The TCJA changed the anitmony rules.

Perhaps the reason could be explained by the Structured Atom Model? Etherealmatters.org and YouTube Channel “See the Pattern”.

That is a pretty wide open question. Care to be more specific?

“What is Swarts Reaction?
Swarts’ reaction is generally used to get alkyl fluorides from alkyl chlorides or alkyl bromides. This is done by heating of the alkyl chloride/bromide in the presence of the fluoride of some heavy metals (silver fluoride or mercurous fluoride for example). The reaction will proceed if sodium fluoride or potassium fluoride is used, but the resulting yield will be significantly lower. This process was first reported by Frederic Jean Edmond Swarts in 1892.”

‘Frédéric Swarts (2 September 1866 – 6 September 1940) was a Belgian chemist who prepared the first chlorofluorocarbon, CF2Cl2 (Freon-12) as well as several other related compounds. He was a professor in the civil engineering at the University of Ghent. In addition to his work on organofluorine chemistry, he authored the textbook “Cours de Chimie Organique.”[1] He was a son of Theodore Swarts (chemist, *1839 Antwerpen; †1911 Kortenberg, Belgium) and a colleague of Leo Baekeland.’

We react Trichloroethylene (C2HCl3) with hydrogen fluoride (HF) to make 1,1,1,2 tetrafluoroethane.

So there are plenty of other methods to Fluorinate.

You are probably limited to ‘swarts reagent’ for Swarts reactions because that is the extent of what is named after Mr. Swarts.

I was just thinking about that this morning while having my coffee.

That is a very specialized question. WTH is a swarts reaction?

;^)

Yes. It’s the Swarts reaction because Swarts found it out.
