N,N′-Bis[trimethylsilyl]-urea: A Useful Silylating Agent for Alcohols and Carboxylic Acids

Silicon‐Assisted Direct Covalent Grafting on Metal Oxide Surfaces: Synthesis and Characterization of Carboxylate N,N′‐Ligands on TiO2

“…The choice for the present study was bis(trimethylsilyl)urea, [48] based on stability, toxicity, and reactivity factors. The trimethylsilylation of the titanium oxide surface (Degussa P-25) was realized with hexamethyldisilazane.…”

Polysulfonylamine, XXXVI Trimethylsilyl-dimesylamin: Darstellung, NMR-spektroskopische Charakterisierung und Reaktionsfähigkeit als Silylierungsreagens / Polysulfonylamines, XXXVI Trimethylsilyl Dimesylamine: Preparation, NMR-Spectroscopic Characterization, and Reactivity as a Silylating Agent

“…Außerdem wird durch die Schwerlöslichkeit des K oprodukts das Gleichgewicht (5) zugunsten der Produktseite verschoben. Ein analoges Verhalten wird im Fall einiger anderer Silylierungsreagenzien als beson ders vorteilhaft hervorgehoben, so für N ,0-B is(trimethylsilyl)sulfamat [19], N,N'-Bis(trimethylsilyl)-harnstoff [20] (6) 5. 1 empfiehlt sich nicht für die N-Silylierung basischer Substrate, z.…”

Tetrabutylammonium bromide promoted efficient and chemoselective trimethylsilylation of primary and secondary alcohols under mild reaction conditions

“…The conversion of hydroxyl groups to their corresponding trimethylsilyl ethers is one of the popular methods used for this purpose. Among the different reagents which are available for the silylation of alcohols [2][3][4], hexamethyldisilazane, as a cheap and commercially available reagent [5,6], is selected as one of the best candidates. Even though the handling of this reagent does not need special precautions and work-up of the reaction mixture is not time consuming, the low silylating power of HMDS is the main drawback for its application [7].…”
