Organoheteroatom stannanes in palladium-catalyzed cross-coupling reactions with 1-naphthyl triflate
(American Chemical Society, 2009-02)
We have studied the Pd-catalyzed cross-coupling reaction of organoheteroatom stannanes containing elements of groups 15 (P, As, Sb) and 16 (Se) with 1-naphthyl triflate (3). The stannanes n-Bu3SnZPh n (Z = P, As, Sb, Se; ...
Perfluoroalkylphosphines and arsines obtained by Pd-catalyzed cross-coupling reaction with organoheteroatom stannanes
(Elsevier Science Sa, 2009-10)
Pd-catalyzed cross-coupling reaction of organoheteroatom stannanes containing elements of the groups 15 (P, As) and 16 (Se) with perfluoroalkyl iodides (RfI) was studied. Herein, a one-pot two-step reaction to form P-Rf, ...
Recent advances in the synthesis of stannanes and the scope of theirposterior chemical transformations
(Elsevier Science Sa, 2014-01)
The SRN1 reactions of trimethylstannyl and triphenylstannyl anions, and other tin nucleophiles with haloarenes are quite versatile. Thus, the SRN1 mechanism can afford triorganylstannyl aromatic compounds which otherwise ...
Highly efficient palladium-catalyzed arsination. Synthesis of a biphenyl arsine ligand and its application to obtain perfluoroalkylarsines
(American Chemical Society, 2009-12)
An efficient one-pot, two-step Pd-catalyzed arsination with n-Bu 3SnAsPh2 (1) and sterically hindered aryl iodides (ArI) with different functional groups is reported. The cross-coupling reactions of this stannane with ArI ...
Highly Efficient Palladium-Catalyzed Arsination on the Way to Arsine Ligands
(Teknoscienze Publisher, 2011-06)
Since arsines are drawing particular attention as ligands in metal-catalyzed reactions, the development of new methods to obtain organoarsines is increasingly recognized as central in the synthesis of new ligands. Transition ...
Bicyclic allyltin derivatives through selective "one pot" hydrostannation - Diels-Alder reaction
(Arkat, 2011-02)
In this paper we report a simple "one pot" procedure to functionalized allyltin derivatives from 1- ethynylcyclohexene. Radical addition of trineophyltin hydride gives quantitatively to (Z,E)-1-(2- trineophylstannylvinyl ...
Synthesis of (Z)-tributylstannyl enynes: systematic studies of Sonogashira cross-coupling reactions between (E)-1-iodovinyl-1-tributylstannanes and terminal acetylenes using amines or tetrabutylammonium hydroxide (TBAOH) as activator
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Sonogashira cross-coupling reactions involving (E)-iodo vinyl stannanes and terminal acetylenes were carried out in the presence of Pd(PPh(3))(4), Cul and several amines, affording (Z)-tributylstannyl enynes in moderate ...
Hydride generation in-atomizer collection atomic absorption spectrometry for the determination of antimony in acetic acid leachates from pewter cups
(2011)
Antimony is one of the constituents of pewter, an alloy composed of a minimum of 90% tin with the balance being made up with copper, antimony and perhaps some bismuth. A method has been developed to determine Sb in acetic ...
