Synthesis of Ethylenic and Acetylenic Triorganotins with Bulky Organic Ligands

The syntheses of trineophyl(1a) and tri-(-)-menthylstannyl phenylacetylene (1b) as well as that of (E)-1-trineophylestannyl-2-phenylethene (2) and (E)-1-trineophylstannyl1,2-diphenylethene (3) are described. The hydrostannation of 1a with an excess of trimethyltin hydride led to 1,1,1-tris(trimethyltin)-2-phenylethane (4) and/or 1,1-bis(trimethyltin)2-phenylethene (5) depending on the reaction ...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Chemical constitution and fungistatic action of organic sulphur compounds.

Elementary sulphur and some of its inorganic compounds have long been of practical importance for the control of parasitic and saprophytic fungi, but the use of organic compounds of sulphur is of more recent origin. Compounds such as tetramethylthiuram disulphide and certain metallic salts of dithiocarbamic acids are now of commercial importance in this connexion (Tisdale & Flenner, 1942; Rober...
