Herein, we report the synthesis of nickel nanoparticles under mild conditions using porous alginate-g-poly(p-styrene sulfonamide-co-acrylamide) as a protecting/stabilizing agent and sodium borohydride as a reducing agent. The porous cross-linked polymeric support was preparedviacombining the use of sol-gel, nanocasting, and crosslinking techniques, in which thep-styrene sulfonamide monomer (PSSA) andN,N′-methylene-bis (acrylamide) (MBA) cross-linker underwent copolymerization on the surface of sodium alginate in the presence of a SiO2nanoparticle (NP) template (Alg-PSSA-co-ACA). The prepared catalyst (Alg-PSSA-co-ACA@Ni) showed high catalytic activity for the one-step synthesis of 1,3,4-oxadiazoles from the reaction of hydrazides and aryl iodides through isocyanide insertion/cyclization.
Iodobenzene diacetate mediated solid-state synthesis of heterocyclyl-1,3,4-oxadiazoles
Rao,Chandra Sekhar

A simple and efficient method has been developed for the oxidation of various heterocyclyl acylhydrazones 3 with iodobenzene diacetate (IBD) to heterocyclyl-1,3,4-oxadiazoles 4 in solid state. The reaction took place at room temperature within few minutes. The products were isolated by simple aqueous work-up in good yields.

Simple N-monosubstituted thioamides react with acid hydrazides to form 1,2,4-triazole derivatives.N,N-Disubstituted thioamides alkylated with methyl iodide readily yield with acid hydrazides 1,3,4-oxadiazoles.
