This was expected based on calculated lower thermodynamic drive for the addition step of the granatanone enol (average [DELTA]G -2.8 for the HB-O and -6.2 kcal/mol for the HB-N) than for the tropinone enol (average [DELTA]G -4.1 for the HB-O and -7.8 kcal/mol for the HB-N).

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.
The silicone-based transformer fluid, Dow Corning 561 Silicone Transformer Liquid (DC561) was manufactured by Dow Corning Limited (Barry, South Glamorgen, UK), and the mineral oil-based transformer fluid, ENOL C, was manufactured by the Oil Rafinery Novi Sad, Yugoslavia.

In our case, both monomer and copolymer showed one absorption band at about 340 nm and 342 nm in the UV spectrum, which is attributed to the intramolecular hydrogen bonded enol isomer.

In contrast to other enolate derivatives, enol phosphates generally have an improved stability, which avoids the formation of side products and also the production of undesirable waste material during the synthesis [10].
And yet Stratford were unlucky not to take an 18th-minute lead when Dan Summerfield's cross from the right was found Will Grocott but his shot struck keeper Enol Ordonez's upright.
