Microencapsulation of reactive isocyanates for application in self-healing materials: a review

Journal of Microencapsulation, 2021
Microencapsulation of curing agents is a major strategy for the development of self-healing polymers. Isocyanates are among the most promising compounds for the development of one-part, catalyst free, self-healing materials, but their microencapsulation ...

Zinc Hydride Catalyzed Chemoselective Hydroboration of Isocyanates: Amide Bond Formation and C=O Bond Cleavage.

Angewandte Chemie, 2021
Herein, a remarkable conjugated bis-guanidinate (CBG) supported zinc hydride, [{LZnH}2; L = {(ArHN)(ArN)-C=N-C=(NAr)(NHAr); Ar = 2,6-Et2-C6H3}] (I) catalyzed partial reduction of heteroallenes via hydroboration is reported.

Isocyanates

Dermatitis, 2012
Owing to the widespread use of isocyanate-derived products across multiple industries, it is important for physicians to be aware of their sensitizing potential. We first provide a general overview of isocyanates and the industries that may be associated with exposure to these compounds.

Rhodium-Catalyzed Synthesis of Amides from Functionalized Blocked Isocyanates

ACS Catalysis, 2019
Isocyanates are useful building blocks for the synthesis of amides, although their widespread use has been limited by their high reactivity, which often results in poor functional group tolerance and a propensity to oligomerize.

Phosphorus Isocyanates

Angewandte Chemie International Edition in English, 1969
AbstractCompounds containing the PNCO grouping can be obtained e.g. from phosphorus halides and silver cyanate or esters of N‐chloroiminocarbonic acid and by thermal decomposition of alkoxycarbonylimino‐phosphoranes. The phosphorus (V) isocyanates resemble the “carbon” isocyanates in their chemical properties, whereas the phosphorus (III) isocyanates ...

WORKERS' EXPOSURE TO ISOCYANATES

American Industrial Hygiene Association Journal, 1992
A model of exposure to isocyanates, based on knowledge of industrial processes and starting materials and the results of industrial hygiene surveys, is proposed. This model of exposure suggests the concentration and physical form of airborne isocyanate monomers and oligomers.
