Über Derivate des Hydrazins, VIII [1] Bis(trimethylsilyl)amino-isocyanat und -isothiocyanat / On Derivatives of Hydrazine, VIII [1] Bis(trimethylsilyl)amino-isocyanate and -isothiocyanate [PDF]

Zeitschrift für Naturforschung B, 1978
Abstract Bis(trimethylsilyl)aminoisocyanate (1) is formed by reaction of the hydrazides LiN2(SiMe3)3 or Li2N2(SiMe3)2 with phosgene. Bis(trimethylsilyl)aminoisothiocyanate (2) is obtained by thermolysis of the hydrazide (Me3Si)3N2CSSLi, which is readily prepared from LiN2(SiMe3)3 and carbon disulfide.

Regioselective multicomponent synthesis of α-boryl ureas: discovery of a potent main protease inhibitor.

Org Biomol Chem
The development of efficient synthetic methods for α-boryl ureas is of significant interest due to their potential as drug-like scaffolds in medicinal chemistry. Herein, we present a multicomponent strategy that transforms α-haloboronates, trimethylsilyl

Selective Conversion of CO2 into Isocyanate by Low-Coordinate Iron Complexes.

Angewandte Chemie, 2018
Discovery of the mechanisms for selective transformations of CO2 into organic compounds is a challenge. Herein, we describe the reaction of low-coordinate Fe silylamide complexes with CO2 to give trimethylsilyl isocyanate and the corresponding Fe ...

Efficient synthesis of 1,2,4-dithiazolidine-3,5-diones [dithiasuccinoyl-amines] from bis(chlorocarbonyl)disulfane plus bis(trimethylsilyl)amines.

Journal of the American Chemical Society, 2005
The 1,2,4-dithiazolidine-3,5-dione heterocycle, also referred to as a dithiasuccinoyl (Dts)-amine, serves as a readily removable amino protecting group for building blocks used in syntheses of peptides, glycopeptides, and PNA; it is also useful as a ...

Metal–silicon triple bonds: reactivity of the silylidyne complexes [Cp*(CO)2M≡Si–Tbb] (M = Cr – W)

Chemical Science
The different reactivity pattern of M≡Si and M≡C bonds (M = transition metal) is illustrated by a series of reactions of the silylidyne complexes [Cp*(CO)2M≡Si–Tbb] (1-M) (M = Cr – W; Cp* = η5-pentamethylcyclopentadienyl; Tbb = 4-tert-butyl-2,6-bis(bis ...
