Oligoimide containing propargyl and phthalonitrile groups in one mol. (OI-PR-PN) was synthesized by a facile and eco-friendly method in benzoic acid melt. To incorporate side propargyl groups into the polyimide backbone, a new monomer was developed – 5-(2-propyn-1-yloxy) benzene-1,3-diamine (PBD). The OI-PR-PN dual-curing behavior was studied by DSC and FT-IR methods. The curing of phthalonitrile groups can be promoted by the intermediates formed during the propargyl groups polymerization This allows crosslinking of phthalonitrile groups at 300-350°C in one component system. OI-PR-PN showed good solubility in low b.p. solvents and had low melt viscosity (up to 8 Pas at 250°C). The temperatures of 10% weight loss of the cross-linked OI-PR-PN and oligoimide containing only propargyl groups (OI-PR) are 496°C and 450°C correspondingly. The completely cured OI-PR-PN glass transition temperature measured by dynamic mech. anal. was 424°C with a storage modulus 4.2 GPa at 50°C. The possibility of crosslinking without using curing additives with a combination of excellent thermal and mech. properties indicates the potential of OI-PR-PN as a matrix for composite manufacturing

A wide range of N-(ethoxycarbonylmethyl)enaminones I (R = 4-O2NC6H4, thiophen-2-yl, tert-Bu, etc.), prepared by the Eschenmoser sulfide contraction between N-(ethoxycarbonylmethyl)pyrrolidine-2-thione and various bromomethyl aryl and heteroaryl ketones RC(O)CH2Br, underwent cyclization in the presence of silica gel to give Et 6-(hetero)aryl-2,3-dihydro-1H-pyrrolizine-5-carboxylates II within minutes upon microwave heating in xylene at 150°C. Instead of functioning as a nucleophile, the enaminone acted as an electrophile at its carbonyl group during the cyclization. Yields of the bicyclic products II were generally above 75%.

Kim, Yoonbin;Kim, Daekyu;Lee, Jeongyeon;Lee, Lawrence Yoon Suk;Ng, Dennis K. P. research published �Tuning the Electrochemical Properties of Polymeric Cobalt Phthalocyanines for Efficient Water Splitting� the research content is summarized as follows. Polymeric metal phthalocyanines have great potential as electrocatalysts, yet their incorporation on a current collector without losing the activity of metal centers remains a challenge. Herein, a new strategy for preparing a series of polymeric cobalt phthalocyanines containing S linkers (pCoPc-1) or SO2 linkers (pCoPc-2) and their tunable electrochem. properties are reported. The pCoPcs coated on various substrates show favorable electrocatalytic activities toward oxygen and hydrogen evolution reactions (OER and HER). Particularly, the pCoPc-1 layer on Co3O4 nanosheet arrays exerts a cooperative effect enhancing both the OER and HER performances, and the subsequent phosphorization (P@pCoPc-1/Co3O4|CC) significantly boosts the HER performance with enhanced hydrophilicity and conductivity The high permeability and stability reinforcement of the pCoPc-1 layer allow the phosphorization of underlying Co3O4 to CoP without degradation, which remarkably enhances OER and HER performances as manifested by low overpotentials of 320 and 120 mV at 10 mA cm-2, resp. When engaged as a bifunctional electrocatalyst for the overall water splitting, the P@pCoPc-1/Co3O4|CC requires a low cell voltage of 1.672 V at 10 mA cm-2, showing long-term durability and mech. robustness. This study demonstrates the collaborative catalytic role of polymeric macrocyclic compounds that offers versatile tunability and stability for various electrocatalytic reactions.

It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals., 31643-49-9.
