Sveriges riksdag added TMA-2 to schedule I ("substances, plant materials and fungi which normally do not have medical use") as narcotics in Sweden as of Dec 30, 1999, published by Medical Products Agency in their regulation LVFS 2004:3 listed as 2,4,5-trimetoxiamfetamin (TMA-2).
Tebbe's reagent, which is used for the methylenation of esters and ketones, is prepared from TMA and titanocene dichloride. [9] In combination with 20 to 100 mol % Cp 2 ZrCl 2 (zirconocene dichloride), the (CH 3) 2 Al-CH 3 adds "across" alkynes to give vinyl aluminium species that are useful in organic synthesis in a reaction known as ...
Trimethylamine (TMA) is an organic compound with the formula N(CH 3) 3. It is a trimethylated derivative of ammonia. TMA is widely used in industry. [5] [6] At higher concentrations it has an ammonia-like odor, and can cause necrosis of mucous membranes on contact. [7] At lower concentrations, it has a "fishy" odor, the odor associated with ...
[2] The synthesis of Al 2 O 3 from trimethylaluminum (TMA) and water is one of the best known thermal ALD examples. During the TMA exposure, TMA dissociatively chemisorbs on the substrate surface and any remaining TMA is pumped out of the chamber. The dissociative chemisorption of TMA leaves a surface covered with AlCH 3.
TMAH undergoes simple acid-base reactions to produce tetramethylammonium (TMA) salts whose anion is derived from the acid used. Illustrative is the preparation of tetramethylammonium fluoride: [6] NMe 4 + OH − + HF → NMe 4 + F − + H 2 O. Solutions of TMAH may be used to make other tetramethylammonium salts in metathesis reactions with ...
Trimethylamine N-oxide (TMAO) is an organic compound with the formula (CH 3) 3 NO. It is in the class of amine oxides.Although the anhydrous compound is known, trimethylamine N-oxide is usually encountered as the dihydrate.
The octanol-water partition coefficient of TMA iodide, P o-w, is 1.2 × 10 −4 (or log P ≈ −3.92). [7] In the TMA cation, the methyl groups are tetrahedrally arranged around the central N atom, as is evident from X-ray crystallographic studies of various of its salts.
Alexander Theodore "Sasha" Shulgin (June 17, 1925 – June 2, 2014) [1] was an American biochemist, broad researcher of synthetic psychoactive compounds, and author of works regarding these, who independently explored the organic chemistry and pharmacology of such agents—in his mid-life and later, many through preparation in his home laboratory, and testing on himself.
