Porous ionic polymers (PIPs) hold significant promise as materials for water purification due to their high specific surface area, adjustable pore structures, and ionic pore channels.
Post-glass melting encapsulation of pyrylium ion based salts in inorganic oxide glasses for the development of advanced optical waveguides.
This review summarizes the synthesis and reactivity of N-aminopyridinium salts, discusses applications in organic synthesis, and highlights the potential for these reagents to enable novel synthetic disconnections and innovations.
Palladium catalyzed Heck-type intramolecular cyclization of N-(2-bromoaryl)pyridinium salts gives pyrido[1,2-a]indoles. A one-pot two-step procedure from pyrylium salts has been developed. The reaction is scalable and affords high product yields.
This review summarizes the development, progress, applications, and future challenges of photocontrolled reversible addition–fragmentation chain transfer (RAFT) polymerization, which has attracted considerable attention in the past several years.
