The impending prodllction limitations on the fully halogenated CFG refrigerants is causing an intense search for possible substitutes. This study reviews the historical development of the CFG refrigerants and the relationship between molecular structure and t:he ozone depletio11 and greenhouse warming potentials. It then demonstrates that the halogenated hydrocarbons (a class of compounds that:...

The aqueous solubilities of a set of 109 hydrocarbons and 132 halogenated hydrocarbons (total 241) are correlated by a three term equation using descriptors calculated solely from molecular structure, with a correlation coefficient (R) of 0.979 and a standard error (s) of 0.386 log units. This equation allows the estimation of aqueous solubilities of hydrocarbons and halogenated hydrocarbons (i...

A unifying stereochemical analysis for the formation of the constitutional isomeric halogenated C(15)-acetogenin medium-ring ether natural products from Laurencia species is presented, where an intramolecular bromonium ion assisted epoxide ring-opening reaction of enantiomerically pure epoxides can account for ring-size, the position of the halogen substituents, and relative and absolute config...

Tetragonal Li 7 La 3 Zr 2 O 12 (LLZO) was halogenated to form cubic LLZOF(Cl) via a low temperature solid state synthetic route using PTFE and PVC polymers.

We here identify by ab initio calculations a new type of three-dimensional (3D) carbon allotropes that consist of phenyl rings connected by linear acetylenic chains in sp+sp(2) bonding networks. These structures are constructed by inserting acetylenic or diacetylenic bonds into an all sp(2)-hybridized rhombohedral polybenzene lattice, and the resulting 3D phenylacetylene and phenyldiacetylene n...
