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 ...
Tetramethylammonium (TMA) is the simplest quaternary ammonium cation. It has the chemical formula [Me 4 N] + and consists of four methyl groups (−CH 3, denoted Me) attached to a central nitrogen atom. The cation is isoelectronic with neopentane (Me 4 C). It is positively-charged and can only be isolated in association with a counter-ion.
[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.
TMA-2 may be: TMA-2 mine; Soyuz TMA-2, a Russian space exploration mission; 2,4,5-trimethoxyamphetamine, a hallucinogenic drug;
The woman accused of stabbing a postal worker to death over a spot in line at a Harlem deli has a long history of knife violence — and once threatened “to cut” one of her previous victims.
A New Jersey man has been charged after a woman's body was found last month in a refrigerator left in a forest, according to multiple outlets. As previously reported, the New Jersey State Police ...
The reduction of TMAO to TMA, catalyzed by TMAO reductase, as part of the electron transport chain follows the following reaction: NADH + H + + trimethylamine N-oxide ⇌ {\displaystyle \rightleftharpoons } NAD + + trimethylamine + H 2 O However, both the R. denitrificans and E. coli enzymes can accept electrons from cytochromes : [ 8 ]
