The primary aim of this article is to update many important synthetic pathways, properties and applications of the polyurethanes and its composites. Polyurethanes (PUs) are a special group of versatile materials with a great potential for different use in the development of modern, healthy and clean society, including its multifaceted use in the fields of construction and building related work, transportation, furniture Read More

The present review article surveys an outline on the most recent efforts and exciting developments (between 2010-2018 years) in the application of chitosan and modified chitosan derivatives as bio support for metal immobilization in the cross coupling reactions. The procedures incorporated in this review comprise metal nanoparticles (Pd, Ni, Cu, Au, Co) or metal ions immobilization on non-modified chitosan, porous chitosan mi Read More

The nucleosides modified in the 2’- and/or 3’-position have been known for years and include important, bioactive compounds such as zidovudine, cytarabine, didanosine, puromycin, and fludarabine. This group consists of analogs with altered configuration, 2’,3’-dideoxy and 2’,3’-dideoxy-didehydro nucleosides, as well as derivatives with additional substituents. These compounds are often targeted against viruses and tum Read More

The PVP and its derivatives have been broadly applied in polymers, organic syntheses, and catalysis processes. The crosslinked PVP is a well-known polymer support for numerous reagents and catalysts. Cross-linked PVPs are commercially available polymers and have attracted much attention over the past due to their interesting properties such as the facile functionalization, high accessibility of functional groups, being nonhyg Read More

Stable nitroxide free radicals have traditionally been associated with 2,2,6,6- tetramethylpiperidine-1-oxyl (TEMPO) or its 4-substituted derivatives as relatively inexpensive and readily accessible compounds with limited possibilities for further chemical modification. Over the past two decades, there has been a resurgence of interest in stable free radicals with proper functionalization tuned for various applications. The objective Read More
