4 C 6 H 5 C(O)CH 3 + NaBH 4 + 4 H 2 O → 4 C 6 H 5 CH(OH)CH 3 + NaOH + B(OH) 3 C 6 H 5 CH(OH)CH 3 → C 6 H 5 CH=CH 2 + H 2 O. A similar two-step process is used industrially, but reduction step is performed by hydrogenation over a copper chromite catalyst: [2] C 6 H 5 C(O)CH 3 + H 2 → C 6 H 5 CH(OH)CH 3. Being prochiral, acetophenone is ...
Alkylation and arylation can be achieved using malonate anions and arenes/ AlCl 3, respectively. Trifluoroacetone has been converted to the dioxirane using oxone. It serves as an oxidizing agent in Oppenauer oxidation. [4] Trifluoracetone is also used in a synthesis of 2-trifluoromethyl-7-azaindoles starting with 2,6-dihalopyridines.
The trifluoromethyl group is a functional group that has the formula-CF 3. The naming of is group is derived from the methyl group (which has the formula -CH 3), by replacing each hydrogen atom by a fluorine atom. Some common examples are trifluoromethane H– CF 3, 1,1,1-trifluoroethane H 3 C – CF 3, and hexafluoroacetone F 3 C –CO– CF 3.
Tetramethyl acetyloctahydronaphthalenes (International Nomenclature for Cosmetic Ingredients name) (1-(1,2,3,4,5,6,7,8-ottaidro-2,3,8,8,-tetrametil-2-naftil)etan-1-one) is a synthetic ketone fragrance also known as OTNE (octahydrotetramethyl acetophenone) and by other commercial trade names such as: Iso E Super, Iso Gamma Super, Anthamber, Amber Fleur, Boisvelone, Iso Ambois, Amberlan, Iso ...
2,3,4,5-Tetrachlorophenol (2,3,4,5-TCP) is a chlorinated derivative of phenol with the molecular formula C 6 H 2 Cl 4 O. References Cited sources. Haynes, William M ...
Pentafluoroethyl iodide can be produced by electrochemical fluorination of 1,1,2,2-tetrafluoro-1,2-diiodoethane. [3] 2 C 2 F 4 I 2 + 2 HF → C 2 F 5 I + I 2 + H 2. It can also be produced by react tetrafluoroethylene, iodine and iodine pentafluoride. [4] 5 C 2 F 4 + 2 I 2 + IF 5 → 5 C 2 F 5 I
Tefluthrin (X=CH 3) is manufactured by the esterification of cyhalothrin acid chloride [6] with 4-methyl-2,3,5,6-tetrafluorobenzyl alcohol. [7] The latter was a novel compound when tefluthrin was invented [ 8 ] and the choice of routes to it has been discussed.
HFO-1234yf has a GWP less than carbon dioxide, [4] [2] itself 1,430 times less potent than R-134a. [5] For this reason, 2,3,3,3‑tetrafluoropropene is the pre-eminent replacement for R-134a in vehicular air conditioners. As of 2022, 90% of new U.S. vehicles are estimated to use HFO-1234yf.
