In 2019,ChemPlusChem included an article by Sivalingam, Soumya; Debsharma, Kingshuk; Dasgupta, Ayan; Sankararaman, Sethuraman; Prasad, Edamana. Formula: C10H7I. The article was titled 《Effect of Slip-Stack Self-Assembly on Aggregation-Induced Emission and Solid-State Luminescence in 1,3-Diarylpropynones》. The information in the text is summarized as follows:

Co-facial stacking can result in aggregation-caused quenching (ACQ) in conjugated organic luminogens. This study provides an attractive ‘slip-stack’ self-assembly approach which can eliminate the occurrence of ACQ. The obtained results from steady-state and time-resolved optical studies, along with X-ray diffraction and computational studies demonstrate aggregation-induced emission enhancement (AIEE) of a donor-π-acceptor based 1,3-diarylpropynone, namely 1-(naphthalenyl)-3-(pyren-1-yl)prop-2-yn-1-one (PYNAP). Unlike the monomer, which exhibits poor photoluminescence in solution (Φf = 2% in ACN), the twisted manifold of PYNAP allows the orientation of the mols. in a slip-stack fashion during the course of aggregation, which not only avoids a direct co-facial arrangement, but also induces augmented rigidity, leading to restricted intramol. rotation (RIR) and enhanced emission quantum yield (Φf = 5% in ACN/H2O). The aggregation behavior of PYNAP’s congener, 1-phenyl-3-(pyren-1-yl)prop-2-yn-1-one (PYPH) reinforces the hypothesis that slip-stack assembly is a useful strategy for AIEE in polycyclic hydrocarbon luminogens. In the experiment, the researchers used many compounds, for example, 1-Iodonaphthalene(cas: 90-14-2Formula: C10H7I)

1-Iodonaphthalene(cas: 90-14-2) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the Simmons–Smith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Formula: C10H7I

An efficient methodol. was developed for C-N cross-coupling reaction between aryl halides and amines using a catalytic system comprised of CuI and N,N-dimethylaminopyridine (DMAP). Coupling reactions were carried out in DMSO at 120°C in the presence of 5 mol% CuI, 20 mol% DMAP and 2.5 equiv of KOH. Addition of DMAP was found to be beneficial in significantly accelerating the reaction rate. Both aryl iodides and aryl bromides were successfully coupled with different primary and secondary amines to furnish the desired cross-coupling product in high yield. A copper complex [Cu(DMAP)4I]I, made by combining CuI and DMAP, was found to produce superior results for the Buchwlad-Hartwig cross-coupling reaction. The use of 2 mol% of the copper complex was sufficient to produce high yields of product.

《Regioselective Cross-Electrophile Coupling of Epoxides and (Hetero)aryl Iodides via Ni/Ti/Photoredox Catalysis》 was published in ACS Catalysis in 2020. These research results belong to Parasram, Marvin; Shields, Benjamin J.; Ahmad, Omar; Knauber, Thomas; Doyle, Abigail G.. Electric Literature of C7H7I The article mentions the following:

A cross-electrophile coupling reaction of epoxides and (hetero)aryl iodides that operates via the merger of three catalytic cycles involving a Ni-, Ti-, and organic photoredox catalyst has been developed. Three distinct classes of epoxides, styrene oxides, cyclic epoxides, and terminal aliphatic epoxides, underwent coupling in moderate to good yield and high regioselectivity with the use of three different nitrogen-based ligands for Ni under otherwise identical reaction conditions. The mild reaction conditions accommodate a broad scope of abundant and complex coupling partners. Mechanistic studies suggest that when styrene oxides are employed radical intermediates are involved via Ti-radical ring opening of the epoxide. Conversely, for terminal aliphatic epoxides, involvement of an iodohydrin intermediate enables the formation of the unexpected linear product.
