Looking for [2,2'-bithiophen]-5-yltrimethyl-stannane
Does anyone know where to buy [2,2'-bithiophen]-5-yltrimethyl-stannane (CAS: 133144-35-1) directly? Can't find it in Sigma-Aldrich. Thanks!

EDIT: Oops. Used the wrong structure. Changed it to reflect the correct one.

Out of curiosity, what is it useful for?

The structure image doesn't correspond the the named compound. Its the 4-nitrophenyl rather than the trimethylstannyl derivative.
The answer to your question is no but have you tried TCI International?

Good point. I just looked at the picture rather than reading carefully.
Interestingly, I am not seeing its full structure here either. Although is is better represented on this site. What gives?
And I would still like to know what it is used for. Organic tin has always seemed to me to be a mysterious beast.

Searching on eMolecules gives only the bis-stannylated compound as commercially available. You might have better luck making it yourself, either by
selective removal of one tin group, or by starting from bithiophene and proceeding via alpha-lithiation and quenching with R3SnCl
@jsum1 - It'll be used for Pd-catalysed coupling (Stille reaction), probably to make extended pi-systems for optoelectronics-type materials. There has
been a lot in the literature on such systems over the past few years.

Do you know of any literature where the synthesis of the product is through removal of one tin group or the other one with alpha-lithiation? I've been
searching a few literature sources and all involve overnight reactions. Preferably trying to search for one that can be done within the day.
