Porous organic polymer with <i>in situ</i> generated palladium nanoparticles as a phase-transfer catalyst for Sonogashira cross-coupling reaction in water
Pd(PPh3)4 catalysed in situ one-pot Suzuki cross-coupling reaction between imidazolium attached dibromobenzene and 1,3,5-tri(4-pinacholatoborolanephenyl)benzene. Besides the high thermal and chemical stability, the obtained Pd@PTC-POP can be used as a highly active and reusable phase-transfer solid catalyst to promote the Sonogashira coupling reaction in water. The obtained results indicate that the Pd@PTC-POP

azaheterocyclic aromatic diphosphonate derivatives of benzimidazole and benzotriazole were synthesized by nickel-catalyzed Arbuzov reaction of 4,7-dibromo-2,1,3-benzothiadiazole with triethylphosphite, followed by reductive sulfur extrusion reaction and cyclization. This new strategy allowed us to obtain these compounds with high efficiency, with the generation of these azaheterocyclic aromatic diphosphonate
A new iridium N-heterocyclic carbene (NHC) metallolinker has been synthesised and introduced into a metal–organic framework (MOF), for the first time, via two different routes: direct synthesis and postsynthetic exchange (PSE).

Three cationic capsule-shaped Zr-based metal–organic polyhedra (MOPs) with different cavity sizes were successfully constructed through the self-assembly of trinuclear zirconocene clusters and imidazolium-functionalized dicarboxylic ligands. Owing to the imidazolium groups in the MOPs, they show good CO2 adsorption uptake. Moreover, the halogen anions of the imidazolium groups and Brønsted acid sites (−OH) in the Zr-based knots are in close proximity, making these MOPs able to catalyze synergistically the cycloaddition reaction of CO2 with epoxides into cyclic carbonates. This is the first report of using MOPs as catalysts for this reaction without the addition of a cocatalyst.
