29684-56-8 Usage


Burgess reagent, a slightly yellow crystalline powder, is a selective dehydrating reagent used in organic synthesis. It is known for its ability to convert secondary and tertiary alcohols, with an adjacent proton, into alkenes. Additionally, it serves as a source of heteroatoms (N, O, S) in organic synthesis, contributing to its synthetic value in medicinal chemistry.


Used in Organic Synthesis:
Burgess reagent is used as a dehydrating agent for the conversion of secondary and tertiary alcohols into alkenes, which is crucial in the synthesis of various organic compounds.
Used in Medicinal Chemistry:
Burgess reagent is used as a synthetic tool in medicinal chemistry, promoting the dehydration of primary amides, formamides, and primary nitroalkanes to generate nitriles, isocyanides, and nitrile oxides, respectively. These transformations are essential for the development of new pharmaceutical compounds.
Used in the Formation of Urethanes:
When Burgess reagent reacts with primary alcohols, it forms urethanes, which have applications in various chemical processes and industries.

Check Digit Verification of cas no

The CAS Registry Mumber 29684-56-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,6,8 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 29684-56:
158 % 10 = 8
So 29684-56-8 is a valid CAS Registry Number.

Crystal Structure of Burgess Inner Salts and their Hydrolyzed Ammonium Sulfaminates

Arduengo, Anthony J.,Uchiyama, Yosuke,DIxon, David A.,Vasiliu, Monica

, p. 867 - 873 (2019/09/03)

The solid-state structures of the Burgess reagent, and its analogous ethyl ester reveal structures indicative of triethylamine solvated sulfonyl imides rather than the more commonly depicted triethylammonium sulfonyl amidate. The existence of a reversibly formed hydrate of Burgess reagent is not supported by present studies, but rather a hydrosylate that does not revert to the Burgess reagent with gentle warming under vacuum was isolated and characterised. Structures of the hydrosylates from both the methyl- and ethyl-amidate esters were determined from X-ray crystallographic analysis and are reported. The crystal structures of the Burgess inner salts exhibit geometries at the sulfur atoms that are intermediate between a planar O2S=NCO2R unit and tetrahedral 4-coordinate sulfur centres that would be expected from a strong single (dative) bond between the triethylamine nitrogen and sulfur. The hydrolysed ammonium sulfaminates are water soluble intermolecular salts composed of triethylammonium ions, Et3NH+, and N-(alkoxycarbonyl)sulfaminate, O(-)SO2NHCO2R {R = CH3 or C2H5}.

A novel, easy and mild preparation of sulfilimines from sulfoxides using the Burgess reagent

Raghavan, Sadagopan,Mustafa, Shaik,Rathore, Kailash

, p. 4256 - 4259 (2008/09/21)

A novel preparation of sulfilimines from the corresponding sulfoxides using the Burgess reagent is described. The reaction is general to dialkyl- and aryl alkyl sulfoxides and proceeds under mild conditions in benzene. A variety of protecting groups can be introduced on the nitrogen of the sulfilimine by choosing the appropriate Burgess reagent.

Stereoselective thermal rearrangement of syn-7-(1,2-Butadienyl)-1-methylbicyclo[2.2.1]hept-2-ene [syn-7-(3-Methylallenyl)-1-methylnorbornene]

Duncan, James A.,Hendricks, Robert T.,Kwong, Katy S.

, p. 8433 - 8442 (2007/10/02)

The synthesis and separate thermal rearrangements of (±)-(1R*,4S*,7S*)-7-[(R*)-1,2-butadienyl]-1- methylbicyclo[2.2.1]hept-2-ene (8a) and (±)-(1R*,4S*,7S*)-7-[(S*)-1,2-butadienyl]-1- methylbicyclo[2.2.1]hept-2-ene (8b) are described. Both 8a and 8b are shown to rearrange to (±)-cis-1-ethylidene-3a,4,5,7a-tetrahydro-6-methylindene (9) and (±)-cis-1-ethylindene-3a,4,5,7a-tetrahydro-3a-methylindene (10) with greater than 90% stereoselectivity. Epimer 8a gives predominantly (E)-9 and (Z)-10, whereas 8b gives predominantly (Z)-9 and (E)-10, results consistent with either a six-electron [σ2s + π2s + π2s] Cope or eight-electron [σ2s + π2s + (π2s + π2a)] augmented Cope process. Stereochemical assignments (8a vs 8b, (E)-9 vs (Z)-9, and (E)-10 vs (Z)-10) are based upon experiments in nuclear Overhauser effect (NOE) difference spectroscopy.
