Oxygen amines

If more than one type of these groups is present such a molecule may be named a hybrid according to Lothrop and Handrick. Groups which do not themselves produce expl props, but may influence them are called auxoplosives by these authors. We may quote hydroxyl, carboxyl, chlorine, sulfur, ether, oxygen, amine, etc. as examples of such groups... 

Some aspects of the photopolymerisation kinetics of different monomers have been investigated. The photopolymerisation rate of methyl methacrylate is accelerated in the presence of oxygen when triethylamine is present . This enhanced rate is associated with the usual oxygen-amine complex which can form a variety of species such as oxygen radical anions or hydrogen peroxide to give reactive hydroxyl radicals. The rate of photopolymerisation of methyl... 

Refinement of the DNA aberration experiments under physiological conditions disclosed further intimacies of the molecular mechanism involved. The chemical backdrop here is that DNA contains a number of nucleophilic sites, chiefly carbonyls, hydroxyls, phosphate oxygens, amines and heterocyclic nitrogens, in addition to those illustrated above. All are potentially reactive against strongly electron-deficient agents. 

Intensities found in the alkyl ion series are also used to validate a heteroatom choice. Since nitrogen provides a better locus for the positive charge than either sulfur or oxygen, amine mass spectra carry a large proportion of the total ion current in the a-deavage ion series, showing only a few... 

A number of monooxygenases are capable of oxygenating amines and thio compounds to hydroxy derivatives and oxides, respectively. The following types of reactions are involved ... 

Ti(OR)4-R3Al-oxygen/amines 1-butene, higher olefins, polymer 345-347... 

Lewis bases are groups that can donate a pair of electrons. This definition is similar to the Bronsted-Lowry definition, but turns out to be broader in scope. Elements with lone pair electrons are all Lewis bases including ethers, carbonyl oxygens, amines, phosphines, and so on. Also anionic species are Lewis bases. Electrons in n-bonds also fall within this definition and...
