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

Nucleophilic Isocyanation [PDF]
ACS Omega, 2020 Abstract Isonitriles are frequently employed as both substrates for organic transformations and ligands for organometallic chemistry. However, despite the wide application of the isonitriles, their synthesis generally depends on the traditional dehydration of N-formamide.

Water-Induced Self-Blown Non-Isocyanate Polyurethane Foams.
Angewandte Chemie, 2022 For 80 years, polyisocyanates and polyols were central building blocks for the industrial fabrication of polyurethane (PU) foams. By their partial hydrolysis, isocyanates release CO 2 that expands the PU network.
