Disilyne with a silicon–silicon triple bond: A new entry to multiple bond chemistry*
The synthesis, crystal structure, and characterization of a silicon–silicon triply bonded species, disilyne with two bis[bis(trimethylsilyl)methyl]isopropylsilyl substituents, are described. The nature of the sp-hybridized silicon atoms is discussed from the viewpoint of spectroscopic results and theoretical calculations. The reactivity of the disilyne with alkali metals, tBuLi, and π-bonded co...
متن کاملUnderstanding the Hydrogen Bond Using Quantum Chemistry
Understanding the origins and the fundamental nature of the chemical bond has been a central focus of chemists for decades. A chemical bond that has received considerable attention due to its importance in biological phenomena and in the relations between gas and condensed phases is the hydrogen bond, typically a relatively weak interaction involving an electronegative donor X, a hydrogen, and ...
متن کاملTriple-bond reactivity of diphosphorus molecules.
We report a mild method for generating the diphosphorus molecule or its synthetic equivalent in homogeneous solution; the P2 allotrope of the element phosphorus is normally obtained only under extreme conditions (for example, from P4 at 1100 kelvin). Diphosphorus is extruded from a niobium complex designed for this purpose and can be trapped efficiently by two equivalents of an organic diene to...
متن کاملEffect of Triple Antibiotic Paste on Bond Strength of Composite to Dentin: An In Vitro Study
Background and Aim: Considering the increasing use of antibiotics in root canal therapy and the possible effects of intracanal medicaments on the bond strength of composite restorations, the aim of this study was to evaluate the effect of triple antibiotic paste (TAP) on shear bond strength of three types of composite resins to dentin. Materials and Methods: In this in-vitro, experimental st...
متن کاملThe fascinating story of boron–boron triple bond
CURRENT SCIENCE, VOL. 104, NO. 12, 25 JUNE 2013 1601 The new international standards are expected to help genebanks worldwide to conserve crop diversity in a more efficient and cost-effective manner. They provide a basis for establishing the norms and standards essential for the smooth operation of a genebank. They can be used by genebank curators as a source of guidance for developing standard...
