932-31-0 Usage

Uses

2-Tolylmagnesium Bromide is an intermediate used in the synthesis of 13-Fluorodibenzo[a,i]pyrene (F588440), which is a polycyclic aromatic hydrocarbon (PAH) thus potentially exhibiting carcinogenic properties through activation of P450 mono-oxygenase enzymes. Also, it has unique electrical and optical properties due to being a conjugated macromolecule.

Check Digit Verification of cas no

The CAS Registry Mumber 932-31-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 932-31:
(5*9)+(4*3)+(3*2)+(2*3)+(1*1)=70
70 % 10 = 0
So 932-31-0 is a valid CAS Registry Number.

Morphology control of selenophene-thiophene block copolymers through side chain engineering

Hollinger, Jon,Seferos, Dwight S.

, p. 5002 - 5009 (2014)

We report the synthesis of three fully π-conjugated diblock copolymers containing selenophene- and thiophene-based repeating units. All of these diblock copolymers undergo phase separation, and by systematically changing the compatibility of the two blocks through side chain modification, we are able to access different thin film morphologies. Introducing a bulky 2-ethylhexyl side chain increases solubility while retaining crystallinity of the selenophene block. While poly(3-hexylselenophene)-b-poly(3-hexylthiophene) and poly(3-(2-ethylhexyl)selenophene-b-poly(3-(2-ethylhexyl)thiophene) form more disordered fibrillar structures, poly(3-hexylthiophene)-b-poly(3-(2-ethylhexyl) selenophene) forms long (1-2 μm) solid state fibrillar structures that are reminiscent of the lamellae that are formed by nonconjugated block copolymers. We further use electron energy loss spectroscopy to visualize thiophene- and selenophene-rich domains at the nanometer scale in each of these examples. By studying new polymer compositions and relating them to solid state structure, we further our understanding of heterocycle induced phase separation and phase separation in general.

Benzylamino side arm-containing half-sandwich fourth subgroup metal complex and application thereof

-

Paragraph 0044-0046, (2021/07/31)

The invention discloses a benzylamino side arm-containing half-sandwich fourth subgroup metal complex as well as a preparation method and application thereof, and the benzylamino side arm-containing half-sandwich fourth subgroup metal complex is activated by a proper cocatalyst and is used for catalyzing ethylene homopolymerization or copolymerization of ethylene and alpha-olefin. By adjusting substituent groups on the ligand and reaction conditions, a copolymer with relatively high molecular weight can be generated during high-activity catalysis of copolymerization of ethylene and alpha-olefin such as propylene, 1-butene, 1-hexene, 1-octene and 1-decene and cycloolefin such as norbornene, ethylidene norbornene and dicyclopentadiene.

Cyclopalladation of telluro ether ligands: Synthesis, reactivity and structural characterization

supporting information, p. 16056 - 16065 (2015/01/09)

Treatment of [PdCl2(PhCN)2] with diaryl telluride in 1:2 molar ratio gave mononuclear palladium complexes, trans-[PdCl2(TeR2)2] (1) (R = Mes (1a) (Mes = 2,4,6-trimethylphenyl), Ph (1b), o-tol (1c) (o-tol = ortho-tolyl)). Reaction of [PdCl2(TeMes2)2] with one equivalent of [PdCl2(PhCN)2] or Na2PdCl4 with TeRR′ afforded chloro-bridged binuclear complexes, [Pd2(μ-Cl)2Cl2(TeRR′)2] (2) (R/R′ = Mes/Mes (2a); Mes/Ph (2b); Ph/Ph (2c)). A toluene-methanol solution of trans-[PdCl2(TeMes2)2] on refluxing for 30 minutes yielded a binuclear cyclopalladated complex, [Pd2(μ-Cl)2{CH2C6H2(4,6-Me2)TeMes)}2] (3). When the refluxing was prolonged, a mononuclear complex cis-[PdCl2{MesTeCH2C6H2(4,6-Me2)TeMes}] (4) was isolated. Treatment of palladium acetate with TeMes2 afforded an acetato-bridged analogue of 3, [Pd2(μ-OAc)2{CH2C6H2(4,6-Me2)TeMes}2] (5a) together with a very minor component, a tetranuclear complex, [Pd(μ-OAc)(μ-TeMes)]4 (6). This reaction with unsymmetrical tellurides, MesTeR, also gave cyclopalladated complexes [Pd2(μ-OAc)2{CH2C6H2(4,6-Me2)TeR}2] (R = o-tol (5b) and Ph (5c)) in which 2-methyl of the mesityl group of the telluride was exclusively metallated. The complex trans-[PdCl2(TeMes2)2] on refluxing in xylene gave palladium telluride, Pd7Te3. These complexes were characterized by elemental analyses, IR and NMR (1H, 13C and 125Te) spectroscopy. The molecular structures of trans-[PdCl2(TeMes2)2] (1a), [Pd2(μ-Cl)2Cl2(TeMes2)2]·2acetone (2a·2acetone), cis-[PdCl2{MesTeCH2C6H2(4,6-Me2)TeMes}] (4), [Pd2(μ-OAc)2{CH2C6H2(4,6-Me2)TeMes)}2]·toluene (5a·toluene), [Pd2(μ-OAc)2{CH2C6H2(4,6-Me2)Tetol-o}2] (5b) and [Pd(μ-OAc)(μ-TeMes)]4 (6) were established by single crystal X-ray diffraction analyses. The mononuclear complex 1a was isolated in two polymorphic forms each with the trans configuration. This journal is
