Clash at the Castle kept WWEs momentum under Triple H moving in the right direction and brought some clarity to the direction of a number of key storylines. When an enolizable ester/ketone is used with a non-enolizable ester, the resulting reaction is known as the crossed Claisen condensation. The aldol reaction is a means of forming carboncarbon bonds in organic chemistry. The benzoin condensation was first reported in 1832 by Justus von Liebig and Friedrich Whler during their research on bitter Another modification of this reaction is the Stobbe condensation reaction, which can proceed with relatively weaker bases.
