Developing an Efficient and General Strategy for Immobilization of Small Molecules onto Microarrays Using Isocyanate Chemistry

Sensors, 2016
Small-molecule microarray (SMM) is an effective platform for identifying lead compounds from large collections of small molecules in drug discovery, and efficient immobilization of molecular compounds is a pre-requisite for the success of such a platform.

Anomeric Amide Enabled Divergent Synthesis of Unsymmetrical Ureas, Carbamates, Thioesters, and Amides From Aldehydes

Angewandte Chemie International Edition, EarlyView.
An anomeric amide‐enabled divergent aldehyde functionalization sequence provides one‐pot access to unsymmetrical ureas, carbamates, thiocarbamates, thioesters, and amides. Key to this transformation is the formation of N‐Boc‐hydroxamate intermediates, which serve as platforms for orthogonal activation via Lossen‐type rearrangements, single‐electron ...

Supramolecular protection of isocyanates from water by encapsulation within hydrophobic crystalline pillar[n]arene macrocycles

Nature Communications
The high reactivity of isocyanate groups not only makes them excellent precursors for polyurethanes and polyureas, but it also leads to their degradation through reactions with atmospheric moisture. Conventionally, blocking reagents containing alcohol or

Determination of phenylurethane and isocyanate groups in isocyanates

, 2020
Reactions of phenylurethane and isocyanate groups of arylisocyanates with secondary amines are studied by IR spectrometry and potentiometric titration. It is found that the rate of the reaction between isocyanate groups and diethylamine is nearly independent of the solvent nature.

Thermal Black‐Infused Polyurethane Rigid Foams: Novel Formulations Toward Higher‐Performance and More Sustainable Insulation

Journal of Applied Polymer Science, EarlyView.
Thermal black improves polyurethane foam structure and stability. It helps the foam rise smoothly while promoting the formation of smaller, more uniform cells. The foam keeps its strength and insulation performance while reducing shrinkage. Its clean production and easy processing make it a sustainable, cost‐effective option for high‐performance ...
