Dehydration of 2, 2, 6, 6-tetramethylolcyclohexanolOlin, John F
The use of cyclohexanol dehydration, isobutane cracking and 2,6-dipn synthesis over dealuminated mordenite to probe acidityThe title probe reactions provided information on the strength and location of acid sites formed after hydrothermal and acid treatment of Mordenite. A generally good correlation was...
In fact, it has been demonstrated that caution should be exercised when synthesizing azodicarboxylic acid dimethyl ester and azodicarboxylic acid diethyl ester (see Non-patent Document 2). (2) For example, when a Mitsunobu reaction in which dehydration condensation is carried out in combination ...

NOTES A NOTE ON THE PREPARATION OF SOME 1-PHENYL-2-NITROETHANOL DERIVATIVES It has been ltnown for many years that aromatic aldehydes (I) and nitromethane (11) will undergo a condensation reaction, under alkaline conditions, to yield the alkali metal derivatives of the aci-form of the mono...
Synthesis and circular dichroism spectra of silver(I) complexes with R , R -DIOP (4 R ,5 R - trans -4,5-bis[(diphenylphosphino)methyl]-2,2-dimethyl-1,3-dio... The title silver(I) complexes as [AgX( R, R-DIOP)] 2 dimers (X=Cl, Br, I or SCN) were synthesized either ...
6-chloro-hexanone/2-/ from dehydration of cyclohexanol to cyclohexene and rearrangements, alkali metal hypochloritedoi:US5498802 AA process for preparing 6-chloro-2-hexanone which comprises the steps of (a) dehydrating cyclohexanol in the presence of a suitable catalyst and at a suitable temperature...
In contrast, the more robust ketones 2,4-dimethyl-3-pentanone, 2,6-dimethylcyclohexanone, and 2-adamantanone, which do not undergo condensation, failed to effect this transformation. Other organooxygen compounds, i.e., methanol, cyclohexanol, 1,2-butene oxide, cyclohexene oxide, DMSO, and Me ...
Synthesis of 1,2,4-oxadiazin-5(6H)-ones from amidoximes and maleic dimethyl ester. Carbonyldiimidazole (CDI) was found to be the appropriate activating agent for the synthesis of 1,2,4-oxadiazoles from amidoximes and carboxylic acids in the NaOH/DMSO medium [97]. Ethyl and isobutyl chlo...
