A green protocol for the in situ synthesis of Pd nanoparticles on chitosan beads (Pd NPs-CS) is reported without need to use any toxic reducing agents. The preparation catalyst was performed using a simple coordination reaction between prepared and palladium ions NPs-CS). obtained characterized by different techniques, including SEM, EDX, DRX, FTIR analyses. NPs-CS investigated Suzuki–Miyaura c...

The aminophosphine-based pincer complexes [C6H3-2,6-{NHP(piperidinyl)2}2Pd(Cl)] (2) and [C6H3-2,6-{OP(piperidinyl)2}2Pd(Cl)] (3) are readily prepared from cheap starting materials by sequential addition of 1,1′,1′′-phosphinetriyltripiperidine and 1,3-diaminobenzene or resorcinol to solutions of [Pd(cod)(Cl)2] (cod = cyclooctadiene) in toluene under N2 in 'one pot'. Compounds 2 and 3 proved to b...

A Pd(0)-catalyzed intramolecular Heck-type reaction of oxime ether has been developed, providing convenient access to heterocyclic oximes.

In this special interview series, we profile members of The FEBS Journal editorial board to highlight their research and perspectives on the journal more. Albert Heck is Professor Chemistry Pharmaceutical Sciences at Utrecht University, Scientific Director Netherlands Proteomics Center, Head Biomolecular Mass Spectrometry group in University since September 1998. He has served as Editorial Boar...

Aqueous Mizoroki-Heck coupling reactions under microwave irradiation (MW) were carried out with a colloidal Pd nanocatalyst stabilized with poly(N-vinylpyrrolidone) (PVP). Many stilbenes and novel heterostilbenes were achieved in good to excellent yields starting from aryl bromides and different olefins. The reaction was carried out in a short reaction time and with low catalyst loading, leadin...

O acoplamento entre haletos de arila e terminais alceno (reação de Heck) foi investigado na presença de catalisadores de paládio (II) suportados em poliestirenos contendo bases de Schiff. O catalisador é estável frente ao ar e umidade, e tem atividade catalítica significativa nas reações de acoplamento cruzado de Heck sob condições normais. Vários haletos de arila e alcenos terminais foram faci...
