The rates of H-atom abstraction by OH radicals and Cl atoms at 298 K from organic compounds are related by the expression log( k (OH)) = (0.412 ± 0.049) log( k (Cl)) (8.16 ± 0.72). The utility of these expressions and the atmospheric chemistry of the title hydrofluoroethe...
T h e combined ether extracts on evaporation gave a syrup (101 ing, 74Yo) which rapidly crystallized. The crystals had a 11ieltiiig point of 117-118' C u~iclepressedon admixture with an authentic specimen of methyl 3,4-anh>rdro-a-~-galactopyrai~os(i1dne.p. 117.5- 118.5" C). ...

Examples are isobutene and the vinyl alkyl ether systems. Monomers of this type are very responsive to cationic type of intiators, such as Lewis acids. Thus, the electron density at the double bond can determine whether a monomer polymerizes via a cationic or an anionic process. A second ...
6 ORGANIC REACTION MECHANISMS Mg CH3Br Et2O CH3MgBr An analogous reagent, known as an alkyllithium, can be prepared by reacting the alkyl bromide with lithium metal in diethyl ether. CH3Br ϩ 2 Li Et2O CH3Li ϩ LiBr In the course of the reactions the carbon atom is reduced from the...
This reaction gives rise to separation problems which may be overcome by the use of a large excess of SO 2 and/or by the addition of suitable organic solvents. The results obtained with SO 2 only and with addition of diethylether and TBP are discussed, also in view of application of ...
