In situ generation of Mes2Mg as a non-nucleophilic carbon-centred base reagent for the efficient one-pot conversion of ketones to silyl enol ethers [PDF]

open access: yes, 2008
Treatment of commercially available MesMgBr with 1,4-dioxane produces the key Mes2Mg reagent in situ which then mediates the deprotonation of ketones to deliver trimethylsilyl enol ethers, at readily accessible temperatures and without any nucleophilic ...

Tetrakis(trimethylsilyl)distiban / Tetrakis (trimethylsilyl) distibane

open access: yesZeitschrift für Naturforschung B, 1979
Abstract Tetrakis(trimethylsilyl)distibane, (Me3Si)4Sb2 is produced by reaction of tris(trimethylsilyl) stibine, (Me3Si)3Sb, with three or less than three equivalents of t-butyl iodide, with trimethyliodosilane, Me3SiI and iodine. The reaction of (Me3Si)3Sb with three or more equivalents of i-butyl iodide and methyl iodide also yields ...

Self-organization of hydrophobic soil and granular surfaces [PDF]

open access: yes, 2007
Soil can become extremely water repellent following forest fires or oil spillages, thus preventing penetration of water and increasing runoff and soil erosion. Here the authors show that evaporation of a droplet from the surface of a hydrophobic granular
