히로유키 야스우다 교수의 연구실은 촉매화학과 고체재료 과학을 중심으로, 초순수 촉매를 활용한 환경 친화적 반응 개발과 고성능 재료의 합성 및 거동 분석을 주요 연구 방향으로 삼고 있습니다. 특히 초임계면 CO₂ 조건에서의 탄소 포집 및 전환 반응, 고도로 선택적인 수소화 반응, 메조다공성 촉매를 통한 유기합성 반응, 그리고 허브 엔트로피 합금의 기계적 거동과 촉매 활성 메커니즘을 다룹니다. 이는 지속 가능한 화학공정과 신소재 개발에 기여하는 기초 연구입니다.

Polyfluoroalkyl phosphonium iodides, Rf3RPI (Rf = C4F9C2H4, C6F13C2H4, C8F17C2H4; R = Me, Rf), catalyzed propylene carbonate synthesis from propylene oxide and carbon dioxide under supercritical CO2 conditions, where propylene carbonate was spontaneously separated out of the supercritical CO2 phase. The Rf3RPI catalyst could be recycled with maintaining a high CO2 pressure and temperature by separating the propylene carbonate from the bottom of the reactor followed by supplying propylene oxide a
Various substituted nitroaromatics were successfully hydrogenated to the corresponding N-aryl hydroxylamines in excellent yields (up to 99%) using supported platinum catalysts such as Pt/SiO2 under a hydrogen atmosphere (1 bar) at room temperature. The key to the fast and highly selective formation of hydroxylamines is the addition of small amounts of amines such as triethylamine and dimethyl sulfoxide; amines promote the conversion of nitroaromatics, while dimethyl sulfoxide inhibits further hy
The presence of the heterogeneous mesoporous Al-MCM-41 catalyst remarkably accelerated the cyanosilylation of various aldehydes and ketones with trialkylsilyl cyanide, giving the corresponding cyanohydrin silyl ethers in quantitative yields under mild reaction conditions.
1,2,3-Trisilacyclopenta-1,4-diene 2, featuring three skeletal Si atoms in the five-membered ring, was synthesized by the thermolysis of the 1,2,3-trisilabicyclo[1.1.0]butane derivative 1 at 130 degrees C in the presence of hex-3-yne. Possessing the properties of nonconjugated cyclopentadiene, 2 readily underwent reduction with KC(8), which was followed by treatment with LiBr to form the lithium salt of 1,2,3-trisilacyclopentadienide 3(-)*[Li(+)(thf)], from which the ketone-coordinated derivative
