Interplay of diruthenium catalyst in controlling enantioselective propargylic substitution reactions with visible light-generated alkyl radicals

Autor: Yulin Zhang, Yoshiaki Tanabe, Shogo Kuriyama, Ken Sakata, Yoshiaki Nishibayashi

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-16 (2023)

Construction of stereogenic carbon centers of propargylic alcohols with free radicals could mark a simple route to molecular complexity from easily obtained starting materials. Here the authors present a strategy to control enantioselective propargyl

Synthesis and Reactivity of Manganese Complexes Bearing Anionic PNP- and PCP-Type Pincer Ligands toward Nitrogen Fixation

Autor: Shogo Kuriyama, Shenglan Wei, Takeru Kato, Yoshiaki Nishibayashi

Publikováno v: Molecules, Vol 27, Iss 7, p 2373 (2022)

A series of manganese complexes bearing an anionic pyrrole-based PNP-type pincer ligand and an anionic benzene-based PCP-type pincer ligand is synthesized and characterized. The reactivity of these complexes toward ammonia formation and silylamine fo

Catalytic transformation of dinitrogen into ammonia and hydrazine by iron-dinitrogen complexes bearing pincer ligand

Autor: Shogo Kuriyama, Kazuya Arashiba, Kazunari Nakajima, Yuki Matsuo, Hiromasa Tanaka, Kazuyuki Ishii, Kazunari Yoshizawa, Yoshiaki Nishibayashi

Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-9 (2016)

Converting dinitrogen into other nitrogen compounds such as ammonia is a difficult task, especially under mild conditions. Here, the authors report a molecular iron complex capable of reducing dinitrogen to both ammonia and hydrazine in a catalytic p
