Several diacetylenic spiroketal enol
ethers known as flosculins A (114), B (115), and C (116), along with five known compounds (117-121) of the same structural class, were isolated from the leaves of Plagius flosculosus.
Indeed, spectral measurements of the film after its heating at 60[degrees]C for 50 min showed that the thermal recovery by proton back-transfer in the usual enol
form occurred into a proportion of around 50% (Fig.
In contrast, for doubly substituted compounds we predict that in some cases (dinitro- and difluorosulphonyl compounds) the enol
form should be predominant and in other cases (dicyano compounds) at least detectable.
Synthesis of optically active [alpha]-hydroxy carbonyl compounds by the catalytic enantioselective oxidation of silyl enol
ethers and ketene acetals with (salen)manganese(III) complexes.
The aim of the present study was to evaluate the acute in vivo and in vitro effects of Askarel, an Arodor 1260-based transformer fluid, and to compare it with the effects of two substitute fluids, the silicone oil-based DC561 and the mineral oil-based ENOL
Preparation of trimethylsilyl, triethylsilyl and tert-butyldimethylsilyl enol

0 min that shows UV absorption at 225 and 275 nm that could correspond to a relatively low molecular weight compound with aldehyde functions or enol
groups of [Beta]-diketones produced as degradation species (15, 16).
In the second half of our fiscal year, we strengthened our presence in Mexico with the acquisitions of VYCMEX and Suministros Industriales Enol
Preparation of trimethylsilyl, triethylsilyl and tert butyldimethylsilyl enol
ethers from ketosteroids for investigations by gaschromatography and mass-spectrometry.
The chemical basis for enhanced adhesion between polymer layers resulting from corona treatment may be due to hydrogen bonding between the -OH of enol
groups and other oxygen containing functional groups created on the polymer surface by the treatment.
CLEVELAND, June 11 /PRNewswire-FirstCall/ -- Applied Industrial Technologies today announced it has successfully completed the acquisition of Suministros Industriales Enol
After evaporation of the solvent, the trimethylsilyl ethers and enol
ethers of the compounds of interest were prepared by reconstituting in 50 [micro]L of MSTFA-N[H.
CLEVELAND, May 14 /PRNewswire-FirstCall/ -- Applied Industrial Technologies today announced it has reached an agreement in principle to acquire Suministros Industriales Enol
Ruthenium-C-TunePhos complexes form excellent catalysts for the asymmetric hydrogenation of beta-ketoesters and enol
