Triazine-hyperbranched polymer-modified magnetic nanoparticles-supported nano-cobalt for C–C cross-coupling reactions

Autor: Abdol R. Hajipour, Shaghayegh Sadeghi

Publikováno v: Journal of the Iranian Chemical Society. 18:3219-3233

Design of hyperbranched polymers (HBPs) and crafting them in catalytic systems especially in organic chemistry are a relatively unexplored domain. This paper reports the utilization of triazine-hyperbranched polymer (THBP)-coated magnetic chitosan na

1,2,3-Triazole framework: a strategic structure for C–H⋯X hydrogen bonding and practical design of an effective Pd-catalyst for carbonylation and carbon–carbon bond formation

Autor: Fatemeh Mohammadsaleh, Seyed Mostafa Hosseini, Khodabakhsh Niknam, Maryam Dehdashti Jahromi, Abdol R. Hajipour

Publikováno v: RSC Advances. 11:20812-20823

1,2,3-Triazole is an interesting N-heterocyclic framework which can act as both a hydrogen bond donor and metal chelator. In the present study, C–H hydrogen bonding of the 1,2,3-triazole ring was surveyed theoretically and the results showed a good

Synthesis of benzimidazoles by two methods (C–H functionalization and condensation reaction) catalyzed by α-zirconium hydrogen phosphate-based nanocatalyst

Autor: Zahra Khorsandi, Saedeh Zakery, Abdol R. Hajipour

Publikováno v: Journal of the Iranian Chemical Society. 17:1919-1931

In this report, two heterogeneous nanocatalysts based on α-zirconium hydrogen phosphate were applied. These heterogeneous catalysts have demonstrated the promising catalytic activity for the synthesis of 2-substituted benzimidazoles in two different
