General Equation: $$ \textR-S-R' + \textR''-B(OH)_2 \xrightarrow\textPd cat., CuTC, Base \textR-R'' + \textByproducts $$

This is the unique feature of this reaction. You can use:

Unlike the Suzuki reaction (which requires a strong base like K$_2$CO$_3$ or Cs$_2$CO$_3$), the Liebeskind coupling often requires no external base or a very weak base. liebeskind 2005 okru verified

If you have found a link claiming to be Liebeskind (2005) on OK.ru, follow these steps to "verify" its safety and quality:

Before diving into the technical aspects of "verified" status or streaming links, it is important to understand the film itself. If “okru” is a typo or misreading (e

In a standard Suzuki coupling, you couple an organoboron with an organic halide (Br, I, Cl). Sulfur compounds were historically incompatible because sulfur binds tightly to palladium, deactivating the catalyst.

Liebeskind’s Solution: Use a copper(I) thiophene-2-carboxylate (CuTC) additive. This copper reagent acts as a "transmetalation shuttle." It binds to the sulfur atom of the electrophile, freeing the palladium and allowing the boronic acid to couple successfully. no match exists. However

If you are searching for the film, here is a method to locate it effectively:

If “okru” is a typo or misreading (e.g., “OK” as in “Oklahoma” or “R.U.” as in “Research Unit”), no match exists. However, a real 2005 Liebeskind paper you might be seeking is:

“The Liebeskind–Srogl Cross-Coupling Reaction and Its Application in Natural Product Synthesis”
Journal of Organic Chemistry, 2005, 70 (23), 9209–9217.

But this contains no “okru” or “verified.”
