Understanding organofluorine chemistry. An introduction to the C-F bond.
Chemical Society Reviews, 2008Fluorine is the most electronegative element in the periodic table. When bound to carbon it forms the strongest bonds in organic chemistry and this makes fluorine substitution attractive for the development of pharmaceuticals and a wide range of ...

Bonds are a species of loan. As evidence of the loan the borrower issues a certificate which in the majority of cases promises the investor a predetermined rate of interest, called the coupon, plus the guarantee of repayment in nominal or cash terms at some future date.

Bond-orientational order in liquids and glasses
, 1983Bond-orientational order in molecular-dynamics simulations of supercooled liquids and in models of metallic glasses is studied. Quadratic and third-order invariants formed from bond spherical harmonics allow quantitative measures of cluster symmetries in

Bond dissociation energies of organic molecules.
Accounts of Chemical Research, 2003In this Account we have compiled a list of reliable bond energies that are based on a set of critically evaluated experiments. A brief description of the three most important experimental techniques for measuring bond energies is provided. We demonstrate

The green bond market: a potential source of climate finance for developing countries
Journal of Sustainable Finance & Investment, 2018This paper examines the potential of green bonds in mobilizing adaptation and mitigation finance for developing countries. Building upon a theoretical approach, it identifies the key drivers of the green bond market over the last few years and the ...

The Chalcogen Bond in Crystalline Solids: A World Parallel to Halogen Bond.
Accounts of Chemical Research, 2019The distribution of the electron density around covalently bonded atoms is anisotropic, and this determines the presence, on atoms surface, of areas of higher and lower electron density where the electrostatic potential is frequently negative and ...

Common Risk Factors in the Cross-Section of Corporate Bond Returns
Journal of Financial Economics, 2018We investigate the cross-sectional determinants of corporate bond returns and find that downside risk is the strongest predictor of future bond returns. We also introduce common risk factors based on the prevalent risk characteristics of corporate bonds ...

Bond-order/bond-length and bond-energy/bond-length relations for carbon-oxygen bonds
Journal of Molecular Spectroscopy, 1961Abstract A bond-order/bond-length relation for carbon—oxygen bonds based on molecular orbital theory is proposed and compared with a bond-energy/bond-length relation based on thermochemical calculations. A reinterpretation of the electronic structure of furan based on the bond-order/bond-length/bond-energy relations is suggested and discussed.

Nonclassical Routes for Amide Bond Formation.
Chemical Reviews, 2016The present review offers an overview of nonclassical (e.g., with no pre- or in situ activation of a carboxylic acid partner) approaches for the construction of amide bonds.
