We report a series of highly stable metallophthalocyanine-based covalent organic frameworks (MPc-dx-COFs) linked by robust 1,4-dioxin bonds constructed through nucleophilic aromatic substitution (SNAr) reaction. The chemical structures and crystallinity of the COFs largely remain unchanged even after treating with boiling water (90 °C), concentrated acids (12 mol/L HCl) or bases (12 mol/L NaOH), oxidizing (30% H2O2) or reducing agents (1 mol/L NaBH4) for three days due to their stable M-Pc building blocks and resilient dioxin linkers. With metallated phthalocyanine active sites regularly arranged in the stable framework structures, MPc-dx-COFs can be directly used as efficient electrocatalysts for the oxygen reduction reaction (ORR) without pyrolysis treatment that has commonly been used in previous studies.
Efficient green procedures for the preparation of novel tetraalkynyl-substituted phthalocyanines

This work provides a successful, easy and efficient process for the preparation of metal-free 2(3),9(10),16(17),23(24)-octamethoxyphthalocyanine, [(OMe)8PcH2] (2), and its metal complexes [(OMe)8PcM] (3-11) (M = Zn, Cu, Ni, Mg, Co, Fe, Ru, TiCl and RhCl) by using green energy techniques such as exposure to UV-irradiation as well as microwave irradiation. Two different routes have been used, which involve modifications to that reported in the literature. The results suggest that these techniques drastically reduce the reaction time of metallophthalocyanine [(OMe)8PcM] (3-11) formation from 5-96 h to 5-11 min. The prepared octamethoxyphthalocyanines [(OMe)8PcM] (2-4) (M = H2, Zn, Cu) are used as key materials to synthesize the corresponding novel tetraalkynyl-substituted phthalocyanines 15-17.

A series of novel (NHC)PdCl2-PR3 complexes were synthesized and fully characterized by 1H, 13C, 31P NMR and FT-IR spectroscopy. These complexes showed high catalytic activity toward solvent-free Buchwald-Hartwig amination. Both primary and secondary amines were efficiently utilized under the same reaction conditions. The solvent-free synthesis of valuable N-aryl carbazoles and similar N-heterocyclic systems was described.
