Tough-to-Swallow Propargylation

tháng 1 26, 2016 , , , , , ,
As I thumbed through the recent Tet Lett abstracts, I encountered this title:
"Regioselective propargylation of aldehydes using potassium allenyltrifluoroborate promoted by tonsil"
Turns out, the authors were referring to Tonsil (R), an acid-treated calcium bentonite clay, not the fleshy pockets in the back of the throat associated with immune response. I guess BRSM  doesn't have to update his "Desperate Conditions" list quite yet...

So, in summary:

This.

Not This.
