چکیده

Reactions between magnesium 1,4-dihydropyridide or 1,2-dihydro-iso-quinolide derivatives and carbodiimides, RN[double bond, length as m-dash]C[double bond, length as m-dash]NR, generally result in Mg-N insertion and formation of guanidinate complexes. More sterically perturbed systems with N-aryl carbodiimide substitution, however, follow a divergent course of reaction initiating heterocyclic ring contraction and pyrrolide formation under unprecedentedly mild conditions.

A Facile Catalytic- Kinetic Method for The Determination of Selenium (IV)

A catalytic-kinetic method for the determination of selenium is proposed. Alizarin navy blue is reduced by sodium sulfide to from a colorless product. The reaction is accelerated by trace amounts of Se (IV), and can be followed by measuring the decrease in absorbance of the dye at 620nm and 30 °C by the fixed time method. Selenium can be determined in the range of 0.004 — 0.12 1.1g.m1-1 . ...

Magnesium hydride-promoted dearomatisation of pyridine.

Reaction of pyridine with well defined magnesium hydride species results in heterocycle dearomatisation by a hydride transfer which occurs with the formation of magnesium compounds containing 1,2- and 1,4-dihydropyridide anions as the respective kinetic and thermodynamic products.

VASTUS MEDIALIS OBLIQUE AND VASTUS LATERALISACTIVITIES RATIO ON SELECTED DEGREES OF RANGE OF MOTION IN OPEN AND CLOSED KINETIC CHAIN DURING ISOMETRIC CONTRACTION

Background: The purpose of this study was to investigate the ratio of Electromyography (EM G) activities of the vastus medialis obliqus (VMO) and vastus lateralis (VL) within seven angles of knee joint range of motion using isometric contraction in open kinetic chain (OK C) and closed kinetic chain (CKC). Methods: The dominant knees of 44 healthy female subjects (mean age: 24.84 with range...

Endo-selective enyne ring-closing metathesis promoted by stereogenic-at-W mono-pyrrolide complexes.

The utility of W-alkylidene complexes for enyne ring-closing metathesis is demonstrated in a direct comparison with Mo-based analogs. Tungsten complexes lead to less alkyne oligomerization and higher levels of endo-selectivity and enantioselectivity.
