Autor: Masato Tsuda, Taiki Morita, Yuto Morita, Jun Takaya, Hiroyuki Nakamura

Publikováno v: Advanced Science, Vol 11, Iss 10, Pp n/a-n/a (2024)

Abstract The nitrogen‐heteroatom single bonds of 1,2‐azoles and isoxazolines underwent methylene insertion in the presence of CH2I2 (6 equiv.) and diethylzinc (3 equiv.) to produce a wide variety of the ring‐expanded six‐membered heterocycles

Improved Conditions for the Visible-Light Driven Hydrocarboxylation by Rh(I) and Photoredox Dual Catalysts Based on the Mechanistic Analyses

Autor: Kei Murata, Nobutsugu Numasawa, Katsuya Shimomaki, Jun Takaya, Nobuharu Iwasawa

Publikováno v: Frontiers in Chemistry, Vol 7 (2019)

The improved catalytic conditions and detailed reaction mechanism of the visible-light driven hydrocarboxylation of alkenes with CO2 by the Rh(I) and photoredox dual catalysts were investigated. The use of the benzimidazoline derivative, BI(OH)H, as
