599-67-7 Usage

Chemical Properties

white to off-white powder or needles

Uses

1,1-Diphenylethanol was used to study the ESR spectra of the spiro-cyclohexadienyl intermediate in the alkoxyl radicals.

General Description

The H-bonds in 1,1-diphenylethanol were studied by means of infrared (IR) absorption spectra.

Purification Methods

Crystallise 1,1-diphenylethanol from n-heptane and/or distil it under vacuum. The benzoyl derivative has m 115o and the phenylurethane has m 119o. [Bromberg et al. J Am Chem Soc 107 83 1985, Beilstein 6 H 685, 6 I 330, 6 II 639, 6 III 3395, 6 IV 4713.]

Check Digit Verification of cas no

The CAS Registry Mumber 599-67-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 599-67:
(5*5)+(4*9)+(3*9)+(2*6)+(1*7)=107
107 % 10 = 7
So 599-67-7 is a valid CAS Registry Number.

Hydroxide-promoted Reduction of the Corrole Complexes of Cobalt(III) and Iron(III) in the Presence of Olefin

Murakami, Yukito,Aoyama, Yasuhiro,Hayashida, Mikio

, p. 501 - 502 (1980)

An oxygenation system effective for electronrich olefins which involves the hydroxide ion, provides electrons required for reduction of the corrole complexes of cobalt(III) and iron(III).

Photochemical polar addition of 1,1-diphenylethene using photosensitive surfactant in stable oil-in-water emulsion

Yoshimi, Yasuharu,Higuchi, Michiya,Itou, Tatsuya,Hatanaka, Minoru

, p. 1196 - 1197 (2004)

An aq NaOH solution of the photosensitive surfactant 1 was mixed with 1,1-diphenylethene 2 to form a stable oil-in-water emulsion and excitation of the emulsion afforded the alcohol 3 in good yield without stirring. The photosensitive surfactant 1 works more efficiently in heterogeneous system (in water) than in homogeneous system (in organic solvent).

PREPARATION AND REACTIONS OF SOLVENT-FREE ARYLCALCIUM HALIDES, ArCaX (X = F, Cl, Br)

Mochida, K.,Ogawa, H.

, p. 131 - 136 (1983)

Reactions of aryl halide vapor and calcium metal vapor were found to give the corresponding arylcalcium halides, ArCaX (X = F, Cl, and Br).Phenylcalcium halide, PhCaX (X = F and Cl), reacted with trimethylchlorosilane to give phenyltrimethylsilane.The reactions of phenylcalcium halides with acetone and benzaldehyde readily gave good yields of 1-methyl-1-phenylethanol and diphenylmethanol, respectively.Phenylcalcium halides reacted slowly with acetonitrile to afford acetophenone in poor yields.With ethyl acetate, phenylcalcium halides gave a mixture of 1,1-diphenylethanol and acetophenone.

Kinetic Isotope Effect and Substituent Effect Study on the Grignard Reaction of MeMgI with Benzophenone. A Rate-Determining C-C Bond Formation

Yamataka, Hiroshi,Matsuyama, Toyoki,Hanafusa, Terukiyo

, p. 647 - 650 (1987)

The carbonyl carbon-14 kinetic isotope effect and substituent effects were determined for the reaction of MeMgI with benzophenone.The observed large carbon isotope effect (14k/12k=1.056) together with the large steric effect on reactivity introduced by o-substituents on benzophenone indicated that the C-C bond formation is the rate-determinig step of the Grignard reaction.

To Rebound or...Rebound? Evidence for the "alternative Rebound" mechanism in Ca'H Oxidations by the systems nonheme Mn Complex/H2O2/carboxylic acid

Ottenbacher, Roman V.,Bryliakova, Anna A.,Shashkov, Mikhail V.,Talsi, Evgenii P.,Bryliakov, Konstantin P.

, p. 5517 - 5524 (2021/05/31)

In this work, it has been shown that aliphatic Ca'H oxidations by bioinspired catalyst systems Mn aminopyridine complex/H2O2/carboxylic acid in acetonitrile afford predominantly a mixture of the corresponding alcohol and the ester. The alcohol/ester ratio is higher for catalysts bearing electron-donating groups at the aminopyridine core. Isotopic labeling studies witness that the oxygen atom of the alcohol originates from the H2O2molecule, while the ester oxygen comes exclusively from the acid. Oxidation of ethylbenzene in the presence of acetic acid affords enantiomerically enriched 1-phenylethanol and 1-phenyl acetate, with close enantioselectivities and the same sign of absolute chirality. Experimental data and density functional theory calculations provide evidence in favor of the rate-limiting benzylic H atom abstraction by the high-spin (S = 1) [LMnV(O)OAc]2+active species followed by competitive OH/OC(O)R rebound. This mechanism has been unprecedented for Ca'H oxidations catalyzed by bioinspired Mn complexes. The trends governing the alcohol/ester ratios have been rationalized in terms of steric properties of the catalyst, acid, and substrate. copy; 2021 American Chemical Society.

Shuttle arylation by Rh(I) catalyzed reversible carbon–carbon bond activation of unstrained alcohols

Lutz, Marius D.R.,Gasser, Valentina C.M.,Morandi, Bill

supporting information, p. 1108 - 1119 (2021/04/19)

The advent of transfer hydrogenation and borrowing hydrogen reactions paved the way to manipulate simple alcohols in previously unthinkable manners and circumvented the need for hydrogen gas. Analogously, transfer hydrocarbylation could greatly increase the versatility of tertiary alcohols. However, this reaction remains unexplored because of the challenges associated with the catalytic cleavage of unactivated C–C bonds. Herein, we report a rhodium(I)-catalyzed shuttle arylation cleaving the C(sp2)–C(sp3) bond in unstrained triaryl alcohols via a redox-neutral β-carbon elimination mechanism. A selective transfer hydrocarbylation of substituted (hetero)aryl groups from tertiary alcohols to ketones was realized, employing benign alcohols as latent C-nucleophiles. All preliminary mechanistic experiments support a reversible β-carbon elimination/migratory insertion mechanism. In a broader context, this novel reactivity offers a new platform for the manipulation of tertiary alcohols in catalysis.

Composition containing diclofenapyr and pretilachlor

-

Paragraph 0015; 0039; 0044-0045; 0053; 0058-0059; 0067; ..., (2021/11/21)

The invention discloses a composition containing diclofenapyr and pretilachlor, which is prepared by wrapping a core material with microencapsulated liquid. When the composition is used, the weed in the paddy field absorbs chitosan, and the chitosan can increase the absorption rate of the weed to the diclofenapyr and the pretilachlor, and the intermediate 9 on the chitosan surface is absorbed by the weed and the rice. , The damage to the rice caused by the diclofenapyr and the pretilachlor is greatly reduced, so that the composition does not affect the rice while killing weeds.
