不安定化学種を研究するなら、実験環境に妥協しちゃ駄目だ。ほんとに駄目。 この1ヶ月、なかなか良いことがないけど、改めてその重要性を痛感した。 気持ちを切り替えていこう。

Hey glovebox experts! Is a dew point of −60 °C still too high for synthesizing highly reactive, low-coordinate species in a newly installed glovebox? We’re seeing a clear boundary. Some compounds still work, while others fail. Unfortunately, we need both! Solvents are great BTW.

Can catalytic skeletal editing shift toward property control? In @ChemRxiv, we discuss this question across a range of organic materials and outline what catalysis could deliver next. Let’s push this chemistry! It was great fun working on this with Sajan and Itami-san @Itamilab!

Can skeletal editing move from structural diversification to property control? Our Perspective on property-directed catalytic skeletal editing of functional organic materials is now on @ChemRxiv. Great work, Taichi @SiAdamas and Sajan! chemrxiv.org/doi/full/10.264…

Toward Property-Directed Catalytic Skeletal Editing of Functional Organic Materials | ChemRxiv

Late-stage skeletal editing has emerged as a useful strategy in synthetic and medicinal chemistry for altering molecular frameworks by atom insertion, deletion, replacement, or bond reorganization....
