A Clinical Investigation of the Use of Promazine Hydrochloride for Pre-Delivery Sedation
… chlorpromazine except that promazine lacks the chlorine atom.

A preliminary study of the characteristic physical properties of chlorinated asphalt
<p>The introduction of chlorine into hydrocarbon compounds produces a product with properties markedly different from those of the original hydrocarbon. Methane, a gas at ordinary conditions, becomes methyl chloride, still a gas but having a higher condensation point than methane, upon the …

Probing the Hydrogen Bonding Interaction at the Gas-Surface Interface using Dispersion Corrected Density Functional Theory
… surface silanol groups and either the sulfur or chlorine atom of the adsorbates, and the calculations indicate that the binding energies for the two hydrogen bond acceptors are similar. The adsorption of sulfur mustard and its mimics on silica also exhibits the presence of significant van der …

Synthesis of [beta]-heteroaryl propionates via trapping of carbocations with [pi]-nucleophiles, efforts towards the total synthesis of acutumine, and the design, synthesis, and thermodynamics of protein-ligand interactions at the Src SH2 domain
… core, two quaternary centers, and a neopentylic chlorine atom, was pursued. A variety of routes were employed, with some of the key steps explored including a Moore cyclization between dimethyl squarate and protected butyn-3-ols, a SmI₂ mediated ring opening of a densely functionalized …

Asymmetrische Synthese von bicyclischen Alpha-Aminosäuren durch intramolekulare Pauson-Khand-Reaktion von l-Alkenylsulfoximinen und Festphasensynthese mit Allylsulfoximinen
… yield. Propargylation at the amino nitrogen atom gave 5-Azaoct-1-en-7-ynes in 91-95% yield. Pauson-Khand Reaction of these Enynes with Co2(CO)8 activated by N-Morpholine-N-oxide (NMO) afforded hexahydrocyclopenta[c]pyridine carboxylic acids with high selectivity (dr up to 98:2) and moderate …

Bound antioxidants in elastomers
… (ECH) rubbers with their reactive chlorine atoms. These reactions take place during high shear mixing in a torque rheometer or in a Winkworth mixer at high temperature or during the vulcanization of the elastomers at 160°C. Mixed alkyl, aryl secondary amines are shown to react only …

Temporal variation, regional sources, and removal processes of volatile organic compounds in New England
… (Appledore Island) site to identify evidence of chlorine initiated oxidation of VOCs, estimate chlorine atom (Cl) concentrations during two summers and for different transport sectors, and assess the potential influence of chlorine chemistry on the oxidative capacity of the troposphere over …

New extended methine dyes for application in laser technology
… intramolecular nucleophilic displacement of the chlorine atom. Thus under suitably forcing reaction conditions intramolecular cyclisation occurred, giving a series of extended donor-acceptor chromophores containing fused heterocyclic residues, the absorption maxima of these new chromophores …

Studies of dichloro- and tetrachloro- adducts of naphthalene and some of its substituted derivatives
… dichloride. Its further reaction with chlorine, under heterolytic conditions gives, in part, a new naphthalene tetrachloride, whose configuration has been assigned, by 1H n.m.r., as being that of the r-1,c-2,c-3,t-4-isomer. The assigned configuration and conformation of the compound are …

Fundamental Studies of the Uptake and Diffusion of Sulfur Mustard Simulants within Zirconium-based Metal-Organic Frameworks
… that 2-CEES forms hydrogen bonds through its chlorine atom likely due to geometric constraints within the MOF pore environment. Temperature-programmed desorption experiments aimed at determining desorption energetics reveal that 2-CEES remain adsorbed within the pores of the MOFs until high …

Secondary organic aerosol formation of relevance to the marine boundary layer
<p>The chlorine atom (Cl) is a potential oxidant of volatile organic compounds (VOCs) in the atmosphere and is hypothesized to lead to secondary organic aerosol (SOA) formation in coastal areas. The purpose of this dissertation is to test this hypothesis and quantify the SOA formation potentials of …
