941-98-0 Usage

Uses

Different sources of media describe the Uses of 941-98-0 differently. You can refer to the following data:
1. 1'-Acetonaphthone is used in the preparation of S(-)-1-(1'-naphthyl) ethanol, an important synthetic intermediate of mevinic acid analog.
2. Used as an abrasive, catalyst, absorbent in petroleum industry, filler for coatings, food additive, ceramics, glass, refractories, electrical insulators and resistors, fluxes, dental cements, and chromatographic applications.

General Description

Stereoselective reduction of 1-acetonapthone in aqueous media by whole cells of Geotrichum candidum has been investigated in various organic co-solvents. Magnetic field effects on the photoinduced electron-transfer reaction between 1-acetonaphthone and diphenylamine in micellar solution have been studied by laser flash photolysis.

Flammability and Explosibility

Notclassified

Safety Profile

Moderately toxic by ingestion. A skin irritant. A combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes

Purification Methods

If the NMR spectrum indicates the presence of impurities, probably 2-acetylnaphthalene, convert the substance to its picrate by dissolving in *benzene or EtOH and adding excess of saturated picric acid in these solvents until separation of picrates is complete. Recrystallise the picrate till the melting point is 118o. Decompose the picrate with dilute NaOH and extract with Et2O. Dry the extract (Na2SO4), filter, evaporate and distil the residue. The 2,4-dinitrophenylhydrazone crystallises from EtOH and has m 259o. [Stobbe & Lenzer Justus Liebigs Ann Chem 380 95 1911, Williams & Osborne J Am Chem Soc 61 3438 1939, Beilstein 7 IV 1292.]

Check Digit Verification of cas no

The CAS Registry Mumber 941-98-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,4 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 941-98:
(5*9)+(4*4)+(3*1)+(2*9)+(1*8)=90
90 % 10 = 0
So 941-98-0 is a valid CAS Registry Number.

Copper-Catalyzed Alkynylation of Benzylic C-H Bonds with Alkynylboronic Esters

Buendia, Mikkel B.,Balin, Jan-Georges J.,Andersen, Mette E.,Lian, Zhong,Kramer, Soren

supporting information, p. 150 - 154 (2021/04/23)

We report a simple method for copper-catalyzed benzylic C-H alkynylation that uses alkynylboronic esters as nucleophilic coupling partners. The catalytic system is readily available and the reaction takes place under mild conditions. Different substrates for the C-H functionalization, as well as various alkynylboronic ester nucleophiles, were evaluated. Finally, three examples of enantioselective C-H alkynylations are presented.

Visible light-mediated, high-efficiency oxidation of benzyl to acetophenone catalyzed by fluorescein

Geng, Haoxing,Liu, Xin,Zhu, Qing

supporting information, (2021/12/20)

An environmentally friendly aerobic oxidation of benzyl C(sp3)-H bonds to ketones via selective oxidation catalysis was developed. Fluorescein is an efficient photocatalyst with excellent chemical selectivity. The reaction has a wide substrate scope, and a successful gram-scale experiment demonstrated its potential industrial utility.

Hydration of Alkynes to Ketones with an Efficient and Practical Polyoxomolybdate-based Cobalt Catalyst

Xie, Ya,Wang, Jingjing,Wang, Yunyun,Han, Sheng,Yu, Han

, p. 4985 - 4989 (2021/10/12)

Hydration of alkynes to ketones is one of the most atom economical and universal methods for the synthesis of carbonyl compounds. However, the basic reaction usually requires organic ligand catalysts or harsh reaction conditions to insert oxygen into the C≡C bond. Here, we report an inorganic ligand supported cobalt (III) catalyst, (NH4)3[CoMo6O18(OH)6], which is supported by a central cobalt (III) mononucleus and a ring-shaped pure inorganic ligand composed of six MoVIO6 octahedrons to avoid the disadvantages of expensive and unrecyclable organic ligand catalysts or noble metal catalysts. Under mild conditions, the cobalt (III) catalyst can be used for the hydration of alkynes to ketones. The catalyst is non-toxic, green, and environment friendly. The catalyst can be recycled at least six times with high activity. According to control experiments, a reasonable mechanism is provided.
