Nowadays, the predominant source for approximately 90% of epoxy resin materials worldwide is diglycidyl ether bisphenol A (DGEBA). However, increasing recognition environmental concerns, such as global warming and depletion petroleum reserves, necessitates exploration alternative options, specifically bio-epoxy derived from sustainable resources. Nonetheless, inadequate flame retardancy presents a notable drawback, limiting its applicability in high-risk environments. The objective this review article to provide concise overview latest up-to-date advances flame-retardant resins sources. Firstly, discussion encompasses inherently bio-based resins, considering both monomers curing agents, focusing on their mechanical properties. Furthermore, utilization phosphorus-containing silicon-containing additives explored. Additionally, comprehensive evaluation partially intrinsically retardant provided. Finally, offers an extensive survey current state-of-the-art field future perspectives, serving valuable resource researchers engaged study

Abstract The development of multifunctional bio‐based materials with closed‐loop chemically recyclable plastics can be a paramount response to the worldwide plastic waste predicament. However, trade‐off dilemma between high performance and easy recycling these still encounters huge challenges. In this contribution, inspired by significant contribution hydrogen bonding networks enhanced mechanical gas barrier as well cosolvents enhance performance, novel polyester material (PBH y F) synthesized monomers that integrate high‐performance efficient chemical is presented. PBH F show ultra‐high properties (83.2 MPa, 233.9%) (CO 2 0.0157 barrer, O 0.0071 H 5.518E‐15 g·cm/cm ·s·Pa) are greater than most engineering previous work. More significantly, also exhibits multifunctionality excellent ultraviolet shielding properties, solvent‐resistant performance. initial obtained in exceptional yields (>90.0%) purity (>99.0%) under mild conditions simple energy‐efficient rapid chemical‐solvolysis strategy, even polyolefin blend plastics. Further possesses similar repolymerized comparable before recycling. Hence, state‐of‐art easy‐recycling provide new approach for green, sustainable economy.

Carbonyl is highly accessible and acts as an essential functional group in chemical synthesis. However, the direct catalytic deoxygenative functionalization of carbonyl compounds via a putative metal carbene intermediate formidable challenge due to requirement high activation energy for cleavage strong C═O double bonds. Here, we report class bench stable readily available Cp*Mo(II)-complexes efficient deoxygenation catalysts that could catalyze intermolecular coupling with alkynes. Enabled by this powerful Cp*Mo(II)-catalyst, various valuable heteroarenes (10 different classes) were obtained generally good yields remarkable chemo- regioselectivities. Mechanistic studies suggested reaction might proceed sequence bonds cleavage, carbene-alkyne metathesis, cyclization, aromatization processes.
