The ROCM reactions of exo- and endo-2-cyano-7-oxanorbornenes with allyl alcohol or allyl acetate promoted by different ruthenium alkylidene catalysts were studied. The stereochemical outcome of the reactions was established. The issues concerning chemo- (ROCM vs ROMP), regio- (1-2- vs 1-3-product formation), and stereo- (E/Z isomerism) selectivity of reactions under various conditions are discu...

Extensive bibliography on isomerism of cyanuric acid is presented. Nine possible isomers of cyanuric acid are characterized computationally. The tri-oxo tautomer is by far the most stable isomer of cyanuric acid. The tri-hydroxy form is by more than 100 kJ mol 1 higher in energy than tri-oxo. Cyanuric acid under all experimental conditions exists as tri-oxo tautomer. g r a p h i c a l a b s t r...

We have read with interest the article titled 'Anatomic Twist to a Straightforward Ablation' authored by Mandeep Singh Randhawa et al [1]. A detailed report of a commendable and unique successful Atrio-Ventricular junction ablation for rapid ventricular-rate control in a patient with Atrial Fibrillation in the setting of left atrial isomerism, common atrium and an interrupted infra-hepatic Infe...
