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 also a popular test substrate for asymmetric hydrogenation experiments.
It is used as a surrogate in place of HCN, as illustrated by its use as a precursor to lithium cyanide: [8] (CH 3) 2 C(OH)CN + LiH → (CH 3) 2 CO + LiCN + H 2. In transhydrocyanation, an equivalent of HCN is transferred from acetone cyanohydrin to another acceptor, with acetone as byproduct. The transfer is an equilibrium process, initiated by ...
Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
Ohio counties (clickable map) This is a list of properties and districts in Ohio that are listed on the National Register of Historic Places. There are over 4,000 in total. Of these, 73 are National Historic Landmarks. There are listings in each of Ohio's 88 counties.
2,2-Dimethoxy-2-phenylacetophenone is a photoinitiator, which is used to initialize radical polymerization e.g. in the preparation of acrylate polymers. [1] Under the influence of light the molecule will form radicals which initiate the radical polymerization. It can also be used as an initiator in the process of making an integrated circuit.
Acetophenone carboxylase (EC 6.4.1.8) is an enzyme with systematic name acetophenone:carbon-dioxide ligase (ADP-forming). [1] This enzyme catalyses the following chemical reaction 2 ATP + acetophenone + HCO 3 − + H 2 O + H + ⇌ {\displaystyle \rightleftharpoons } 2 ADP + 2 phosphate + 3-oxo-3-phenylpropanoate
Many kinds of diketones are known, some with unusual properties. The simplest is diacetyl (CH 3 C(O)C(O)CH 3 ) , once used as butter-flavoring in popcorn . Acetylacetone (pentane-2,4-dione) is virtually a misnomer (inappropriate name) because this species exists mainly as the monoenol CH 3 C(O)CH=C(OH)CH 3 .
In organic chemistry, enols are a type of functional group or intermediate in organic chemistry containing a group with the formula C=C(OH) (R = many substituents). The term enol is an abbreviation of alkenol, a portmanteau deriving from "-ene"/"alkene" and the "-ol". Many kinds of enols are known. [1]
