Atmospheric trace gases and aerosols and climate interact in many ways. A quantitative assessment of the influence of trace gases and aerosols on climate can only be achieved if the interactions and feedbacks among these three major components are accounte ...
Two new aminophosphines, benzyl-N(Ph2P)(2) and 2-picolyl-N(Ph2P)(2), have been synthesized. Oxidation of the aminophosphines with either hydrogen peroxide, elemental sulfur and selenium gave the corresponding oxides, sulfides and selenides benzyl-N(Ph2P=E) ...
N,N-Bis(diphenylphosphino)ethylaniline compounds, Ph2PN-C6H4-C2H5, with ethyl groups at the ortho- and para-positions have been synthesized. Oxidation of the aminophosphines with hydrogen peroxide, elemental sulfur and selenium gave the corresponding ...
The use of gold nanoparticles as biological probes requires the improvement of colloidal stability. Dihydrolipoic acid (DHLA), a dithiol obtained by the reduction of thioctic acid, appears therefore very attractive for the stabilization and the further fun ...
Dihydrolipoic acid ( DHLA) capped gold nanoparticles (Au@DHLA) are characterized in solid and liquid states by sulfur K-edge XANES spectroscopy; it clearly shows that DHLA is anchored to gold thanks to both sulfur ends. ...
The polydentate phosphinoamines 1,3-{(Ph2P)(2)N}(2)C6H4 and 2,6-{(Ph2P)(2)N}(2)C5H3N have been prepared in a single step from the reaction of the amines 1,3-(NH2)(2)C6H4 or 2,6-(NH2)(2)C5H3N with Ph2PCl in presence of Et3N (1:4:4 molar ratio) in CH2Cl2. Re ...
Natural polyketides show important biological activity. The inherent stereochemical complexity present in this class of molecules has captured the imagination of organic chemists. Their stereocontrolled, asymmetric total synthesis is a permanent and stimul ...
The attempt to prep. hitherto unknown homopolyat. cations of sulfur by the reaction of elemental sulfur with blue S8(AsF6)2 in liq. SO2/SO2ClF, led to red (in transmitted light) crystals identified crystallog. as S8(AsF6)2. The X-ray structure of this salt ...
Profiles of the major sulfur functional groups in mature Norway spruce wood tissue have been established for the first time. The big challenge was the development of a method suitable for sulfur speciation in samples with very low sulfur content (
The energetics of dissocn. reactions of S82+ into stoichiometric mixts. of Sn+, n = 2-7, and Sm2+, m = 3, 4, 6, 10, were investigated by the B3PW91 method [6-311+G(3df)//6-311+G*] in the gas phase and in soln., with solvation energies calcd. using the SCIP ...
