Fast Amide Bond Cleavage Assisted by a Secondary Amino and a Carboxyl Group-A Model for yet Unknown Peptidases?
Unconstrained amides that undergo fast hydrolysis under mild conditions are valuable sources of information about how amide bonds may be activated in enzymatic transformations. We report a compound possessing an unconstrained...

Rockefeller University Research Profiles are a series of scientific profiles that were published quarterly, from 1980-1990, by the Rockefeller University. Each issue features the research and achievements of an individual...
Selective Dealkenylative Functionalization of Styrenes via C-C Bond Cleavage.
As a readily available feedstock, styrene with about 25 million tons of global annual production serves as an important building block and organic synthon for the synthesis of fine chemicals, polystyrene plastics, and...

Coordination chemistry of the bench-stable tris-2-pyridyl pnictogen ligands [E(6-Me-2-py)3] (E = As, As[double bond, length as m-dash]O, Sb).
Tripodal ligands with main group bridghead units are well established in coordination chemistry and single-site organometallic catalysis. Although a large number of tris(2-pyridyl) main group ligands [E(2-py)3] (E = main group...

Bond graph-based filtered inversion of multivariable physical systems
Roger F Ngwompo
Jan 01, 2012
In a variety of fields, system inversion is often required in order to determine inputs from measured or for desired outputs. However, inverse systems are often non-proper in the sense that they require differentiators in their...

The Alchemy of Diversification: A Deep Dive Into the Stock-Bond Correlation
Evan Coffey
Jan 01, 0001
This research delves into the intricate dynamics of the stock-bond correlation, seeking to reveal the underlying factors that drive its fluctuations. Through a comprehensive analysis of empirical data, it investigates the...

Effect of Liquidity, Productivity and Firm Size on Bond Ranking
The purpose of this research was to analyze the effect of liquidity, productivity and firm size on bond ratings on non financial companies in ranked PT PEFINDO and listed on the Indonesia Stock Exchange in the period...
Double insertion of CO2 into an Al–Te multiple bond


We report the [Al(NONDipp)(Te)(THF)]− anion containing a terminal aluminium telluride bond. DFT calculations confirm appreciable Al–Te multiple bond character and reaction with CO2 proceeds via a double insertion to...

Mode switching in causally dynamic hybrid bond graphs
R. Margetts, R. F. Ngwompo
Jun 01, 2015

The causally dynamic hybrid bond graph is extended to the case of mode-switching behaviour. Mode-switching 'trees' of switches and elements are historically used by bond graph practitioners to represent elements with...

A versatile hard-soft N/S-ligand for metal coordination and cluster formation.
Deprotonation of the thialdiphosphazane [S[double bond, length as m-dash]PH(μ-N(t)Bu)]2 with a range of metal-bases gives the stable dianion [S-P(μ-N(t)Bu)]2(2-), which is valence-isoelectronic with the widely-used...

Floer Simple Manifolds and L-Space Intervals
J Rasmussen, SD Rasmussen
Feb 26, 2018
An oriented three-manifold with torus boundary admits either no L-space Dehn filling, a unique L-space filling, or an interval of L-space fillings. In the latter case, which we call “Floer simple,” we construct an invariant...
