Amide coupling is one of the most common reactions in organic chemistry and DMTMM is one reagent used for that reaction. The mechanism of DMTMM coupling is similar to other common amide coupling reactions involving activated carboxylic acids. [1] Its precursor, 2-chloro-4,6,-dimethoxy-1,3,5-triazine (CDMT), has also been used for amide coupling.
2,4-Dimethoxybenzaldehyde (DMBA) is a reagent used to specifically quantify phlorotannins. This product reacts specifically with 1,3-and 1,3,5-substituted phenols (e.g., phlorotannins) to form a colored product.
Isoapiole is then nitrated via a Knoevenagel condensation to 2-nitro-isoapiole or 1-(2,3-dimethoxy-3,4-methylenedioxyphenyl)-2-nitropropene by adding it to a stirred solution of acetone and pyridine at ice-bath temperatures and treating the solution with tetranitromethane. The pyridine acts as a catalyst in this reaction.
[1] Methylation of 5-nitrovanillin. In early work on psychoactive phenethylamines, [1] 3,4-dimethoxy-5-nitrobenzaldehyde was condensed with nitromethane in a Knoevenagel reaction to give the corresponding nitrostyrene, which is reduced electrochemically to yield the corresponding β-phenylethylamine. Knoevenagel condensation with 5-nitrovanillin
The reaction is named after its co-discoverer, John E. McMurry. The McMurry reaction originally involved the use of a mixture TiCl 3 and LiAlH 4, which produces the active reagents. Related species have been developed involving the combination of TiCl 3 or TiCl 4 with various other reducing agents, including potassium, zinc, and magnesium.

This group typically excludes compounds in which either benzene is fused to another ring (bicyclic, tricyclic, polycyclic) [1] or includes a heteroatom, or where the methane connects to three or four benzenes. Ball-and-stick model of the benzhydryl radical. The benzhydryl radical can be abbreviated Ph 2 CH• or Bzh. [2]
