The betain-like carbodiphosphorane CS2 adduct S2CC(PPh3)2 (1) reacts with Ag(I) salts which contain weakly coordinating anions such as [BF4]- or [Al{OC(CF3)3}4]- to produce the cluster compounds [Ag6{S2CC(PPh3)2}4][BF4]6 (2) and [Ag4{S2CC(PPh3)2}4][Al{OC(C ...
Synthesis, properties and reactions of two isomeric dipyrido-1,4-dithiins of the C-2h and C-2v symmetry are described. Their structure detennination and identification are based on spectroscopic methods (H-1 and C-13 NMR, HETCOR, gHMBC and MS), physical pr ...
The cationic complexes [(η6-arene)Ru(SC5H4NH)3]2+, arene being C6H6 (1), MeC6H5 (2), p-iPrC6H4Me (3) or C6Me6 (4), have been synthesized from the reaction of 4-pyridinethiol with the corresponding precursor (η6-arene)2Ru2(μ2-Cl)2Cl2 and isolated as the chl ...
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 ...
Under appropriate conditions sulfur dioxide reacts with 1,3-dienes in the hetero-Diels-Alder fashion. In the case of 1-alkoxy-1,3-dienes the 6-alkoxy-3,6-dihydro-1,2-oxatiin-2-oxides (sultines) so-obtained can be ionized in the presence of Lewis or protic ...
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 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 ...
Under appropriate conditions sulfur dioxide reacts with 1,3-dienes in a hetero-Diels-Alder fashion. In the case of 1-alkoxy-1,3-dienes the 6-alkoxy-3,6-dihydro-1,2-oxathiin-2-oxides (sultines) so-obtained can be ionized in the presence of Lewis or protic a ...
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. ...
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 ...
