729-81-7 Usage

Uses

1,3,5-tris(trifluoromethyl)benzene was used as a starting material in the synthesis of bis(2,4,6-tris(trifluoromethyl)phenyl)chloropnictines.It may be used as a starting material in the synthesis of 2,4,6-tris(trifluoromethyl)benzoic acid by reacting with n-butyllithium and carbon dioxide and in the synthesis of lithio derivative, via direct metalation with n-butyllithium.

General Description

1,3,5-tris(trifluoromethyl)benzene is a tri-substituted benzene. It has been synthesized by reacting benzene-1,3,5-tricarboxylic acid with SF4. Reports suggest that 1,3,5-tris(trifluoromethyl)benzene is a nonanesthetics and shows convulsant properties. Its vapor absorption spectra and corresponding solution spectra has been investigated. Its reaction with methyl lithium has been analyzed using semiempirical reaction modelling.

Check Digit Verification of cas no

The CAS Registry Mumber 729-81-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 729-81:
(5*7)+(4*2)+(3*9)+(2*8)+(1*1)=87
87 % 10 = 7
So 729-81-7 is a valid CAS Registry Number.

Cross-Coupling through Ag(I)/Ag(III) Redox Manifold

Demonti, Luca,Mézailles, Nicolas,Nebra, Noel,Saffon-Merceron, Nathalie

supporting information, p. 15396 - 15405 (2021/10/12)

In ample variety of transformations, the presence of silver as an additive or co-catalyst is believed to be innocuous for the efficiency of the operating metal catalyst. Even though Ag additives are required often as coupling partners, oxidants or halide scavengers, its role as a catalytically competent species is widely neglected in cross-coupling reactions. Most likely, this is due to the erroneously assumed incapacity of Ag to undergo 2e? redox steps. Definite proof is herein provided for the required elementary steps to accomplish the oxidative trifluoromethylation of arenes through AgI/AgIII redox catalysis (i. e. CEL coupling), namely: i) easy AgI/AgIII 2e? oxidation mediated by air; ii) bpy/phen ligation to AgIII; iii) boron-to-AgIII aryl transfer; and iv) ulterior reductive elimination of benzotrifluorides from an [aryl-AgIII-CF3] fragment. More precisely, an ultimate entry and full characterization of organosilver(III) compounds [K]+[AgIII(CF3)4]? (K-1), [(bpy)AgIII(CF3)3] (2) and [(phen)AgIII(CF3)3] (3), is described. The utility of 3 in cross-coupling has been showcased unambiguously, and a large variety of arylboron compounds was trifluoromethylated via [AgIII(aryl)(CF3)3]? intermediates. This work breaks with old stereotypes and misconceptions regarding the inability of Ag to undergo cross-coupling by itself.

1-bromo-3,5-bis(trifhioromethyl)benzene: A versatile starting material for organometallic synthesis

Porwisiak, Jacek,Schlosser, Manfred

, p. 233 - 235 (2007/10/02)

1-Bromo-3,5-bis(trifluoromethyl)benzene (1) can be selectively prepared by treatment of 1,3-bis(fluorornethyl)benzene with N,N′-dibromo-5,5-dimethylhydantoin in strongly acidic media. A number of synthetically useful reactions via 3,5bis{trifluoromethyl)phenylmagnesium, -lithium, and -copper intermediates were accomplished. VCH Verlagsgesellschaft mbH, , 1996.

TRIFLUORMETHYLIERUNGSREAKTIONEN VON Te(CF3)2 MIT HALOGENBENZOLEN UND METHYLBENZOLEN

Naumann, Dieter,Kischkewitz, Jurgen

, p. 283 - 299 (2007/10/02)

Substituent effects on yields and regioselectivity of photochemical and thermal trifluoromethylation reactions of Te(CF3)2 with halogen benzenes and methyl benzenes are investigated under comparable conditions.All reactions lead to trifluoromethylated products.The yields of the thermal are always higher than those of the corresponding photochemical reactions.The reactivity of the halobenzenes increases in the series C6H5-F a sidereaction, but H-substitution is the primary reaction pathway.During the reactions with iodobenzene tellurium containing compounds are also formed.The reactions with methyl benzenes show an increase in reactivity in the series hexamethylbenzene mesitylene toluene p-xylene.In all cases only ring substituted products are detected.Reactions with toluene and p-xylene yield tellurium containing compounds as well as addition products.The 19F-n.m.r spectra of the products are given.
