Recent Advances in Fabrication of Non-Isocyanate Polyurethane-Based Composite Materials.
Stachak P, Łukaszewska I, Hebda E, Pielichowski K. Stachak P, et al. Materials (Basel). 2021 Jun 23;14(13):3497. doi: 10.3390/ma14133497. Materials (Basel). 2021. PMID: 34201649 Free PMC article. Review.
Polyurethanes (PUs) are a significant group of polymeric materials that, due to their outstanding mechanical, chemical, and physical properties, are used in a wide range of applications. Conventionally, PUs are obtained in polyaddition reactions between diisocyanates and p …

A facile synthesis of sulfonylureas via water assisted preparation of carbamates.
Tanwar DK, Ratan A, Gill MS. Tanwar DK, et al. Org Biomol Chem. 2017 Jun 14;15(23):4992-4999. doi: 10.1039/c7ob00872d. Org Biomol Chem. 2017. PMID: 28567464
The first reaction of diphenyl carbonate with amines was carried out in aqueous : organic (H(2)O : THF, 90 : 10) medium at room temperature to produce carbamates that paved a straightforward route to sulfonylureas after reaction with sulfonamides. The above p …
