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]

open access: hybridZeitschrift 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.

Kinetic and chemorheological modeling of thermosetting polyurethanes obtained from an epoxidized soybean oil polyol crosslinked with glycerin [PDF]

open access: yesarXiv, 2022
Thermosetting polyurethanes were obtained using an aromatic isocyanate and a hydrophobic polyol formulation obtained from epoxidized soybean oil (ESO) crosslinked with glycerin. A systematic DSC analysis of the effect of catalyst type, crosslinker concentration, isocyanate index and ESO crystallization on the cure kinetics was conducted.

Exploring the transport properties of equatorially low coordinated erbium single ion magnets [PDF]

open access: yes, 2019
Single-molecule spin transport represents the lower limit of miniaturization of spintronic devices. These experiments, although extremely challenging, are key to understand the magneto-electronic properties of a molecule in a junction. In this context, theoretical screening of new magnetic molecules provides invaluable knowledge before carrying out ...

Identification of Methyl Isocyanate and Other Complex Organic Molecules in a Hot Molecular Core, G31.41+0.31 [PDF]

open access: yes, 2020
G31.41+0.31 is a well known chemically rich hot molecular core (HMC). Using Band 3 observations of Atacama Large Millimeter Array (ALMA), we have analyzed the chemical and physical properties of the source. We have identified methyl isocyanate (CH3NCO), a precursor of prebiotic molecules, towards the source.

Total Synthesis of Kanamycins

open access: yesChemistry – A European Journal, Accepted Article.
Structurally‐modified aminoglycosides, such as kanamycin, have shown promise as antibiotics and premature termination codon read‐through drugs to fight against drug‐resistant bacteria and to treat genetic diseases, respectively. Therefore, research on developing and discovering aminoglycoside antibiotics has recently increased.

Solvation chemistry in liquid electrolytes for rechargeable lithium batteries at low temperatures

open access: yesEcoEnergy, EarlyView.
This review discusses the solvation chemistry of the electrolyte in lithium batteries (LBs) at low temperature (LT). It highlights the Li+ solvation chemistry in LBs at LT, including the properties of the solvent, the solvation structure of Li+, strategies of tuning solvation chemistry via solvents/lithium salts, and characterization techniques of ...

Reactivity of an ortho‐Phenylene‐bridged Al/P Frustrated Lewis Pair Towards Small Molecules

open access: yesEuropean Journal of Inorganic Chemistry, Accepted Article.
Frustrated Lewis Pairs (FLPs) as ambiphilic molecules are prone to activate small molecules and are in the focus of interest for many years. In this paper, we present the first ortho‐phenylene bridged Al/P‐based FLP with only one phosphine moiety. The title compound was employed in various reactions with small molecules featuring different functional ...

Re-exploring Molecular Complexity with ALMA (ReMoCA): Interstellar detection of urea [PDF]

open access: yesA&A 628, A10 (2019), 2019
Urea, NH2C(O)NH2, is a molecule of great importance in organic chemistry and biology. Two searches for urea in the interstellar medium were reported in the past, but neither were conclusive. We want to take advantage of the increased sensitivity and angular resolution provided by ALMA to search for urea toward the hot cores embedded in the high-mass ...

Synthesis of Oligo‐ and Polyethylene‐Polyamide‐6 Diblock Polymers

open access: yesJournal of Polymer Science, EarlyView.
ABSTRACT A route for the development of a potential filament material for FFF 3D printing based on HDPE‐PA‐6 diblock copolymers is described. The approach consists of inducing an anionic caprolactam polymerization using a hydroxy‐functionalized polyethylene macroinitiator.
