Light-induced electron transfer/phase migration of a redox mediator for photocatalytic C–C coupling in a biphasic solution

Autor: Ren Itagaki, Shin-ya Takizawa, Ho-Chol Chang, Akinobu Nakada

Publikováno v: Dalton Transactions. 51:9467-9476

Photocatalytic molecular conversions that lead to value-added chemicals are of considerable interest. To achieve highly efficient photocatalytic reactions, it is equally important as it is challenging to construct systems that enable effective charge

Synthesis of Microporous Aluminosilicate by Direct Thermal Activation of Phenyl-Substituted Single-Source Aluminosilicate Molecular Precursors

Autor: Akira Imaizumi, Akinobu Nakada, Takeshi Matsumoto, Toshiyuki Yokoi, Ho-Chol Chang

Publikováno v: Inorganic chemistry. 61(34)

The construction of aluminosilicates from versatile molecular precursors (MPs) represents a promising alternative strategy to conventional processes based on monomeric molecular or polymeric Al and Si sources. However, the use of MPs often suffers fr

Functional Group-Directed Photochemical Reactions of Aromatic Alcohols, Amines, and Thiols Triggered by Excited-State Hydrogen Detachment: Additive-free Oligomerization, Disulfidation, and C(sp2)–H Carboxylation with CO2

Autor: Kanae Abe, Akinobu Nakada, Takeshi Matsumoto, Hirotoshi Mori, Ho-Chol Chang, Daiki Uchijyo

Publikováno v: The Journal of Organic Chemistry. 86:959-969

Exploring new types of photochemical reactions is of great interest in the field of synthetic chemistry. Although excited-state hydrogen detachment (ESHD) represents a promising prospective template for additive-free photochemical reactions, applicat

Excited-state hydrogen detachment from a tris-(o-phenylenediamine) iron(ii) complex in THF at room temperature

Autor: Takuji Koike, Ho-Chol Chang, Takeshi Matsumoto, Akinobu Nakada

Publikováno v: Chemical Communications. 56:15414-15417

We previously reported that a tris-(o-phenylenediamine) iron(II) complex promotes photochemical H2 generation and C–H carboxylation of o-phenylenediamine without any additives under N2 and CO2 atmospheres, respectively, in tetrahydrofuran at room t

Facile and selective synthesis of zeolites L and W from a single-source heptanuclear aluminosilicate precursor

Autor: Akinobu Nakada, Akira Imaizumi, Ho-Chol Chang, Takeshi Matsumoto

Publikováno v: CrystEngComm. 22:5862-5870

Zeolites are usually synthesized by hydrothermal reactions using monomeric or polymeric Al- and Si-containing precursors, whereas simple and direct routes for the rational synthesis of zeolites remain elusive. In this work, we demonstrate the synthes
