Goldberg  /  2d  //  keep unread  //  hide  //  preview   http://pubs.acs.org/doi/pdf/10.1021/jacs.5b05142 Isomorphous crystals of Mn V (O) and Cr V (O) corrolazines were characterized by single crystal X-ray diffraction. Reactivity studies with H atom donors and separated PCET reagents show a dramatic difference in H atom abstracting abilities for these two complexes. The implied large difference in driving force is opposite the trend in redox potentials, indicating that basicity is a key factor in determining the striking difference in reactivity for two metal-oxo species in identical ligand environments.  Journal of the American Chemical Society DOI: 10.1021/jacs.5b05142 Visit Website

Mechanistic implications have been analysed with the aid of computational methods.

The results indicate that the CO adduct of Rh octaethylporphyrin is vulnerable to nucleophilic attack by H 2 O.

（タイトルは ホッテントリーメーカー より） とある 先生（ 筑波大学、落合博士 ）の、論文内の情報を整理するための フレームワーク が話題になっています。 [参照： 高速で論文がバリバリ読める落合先生のフォーマットがいい感じだったのでメモ ] どんなもの？ 　 (cf. 銅スーパーオキシド種を単離した) 先行研究と比べてどこがすごい？　 (cf. スペクトルはあっても構造は無かった) 技術や手法のキモはどこ？　 (cf. 立体障害の大きいリガンドを利用して安定化した) どうやって有効だと検証した？　 (cf. 単結晶X線構造解析を行った)　 議論はある？　 (cf. 反応性は？) 次に読むべき論文は？ 　(cf. Niでは？Feでは？ ) 「 このフォーマットに従って問いを埋めていくだけで、論文ひとつの内容をA4半分～1枚に圧縮できる。これで出来上がるものはその論文の「オレオレ要旨」ともいえるものだ。 （上記ブログより）」 たしかにそうだと思います。 論文では、明言できないところは書かない(書けない)のですが、上記の問いについて、書かれていない所については、自分で考えてみてもよいですね。 メソッドを習得したいときの論文の読み方というより、もうすこしコンセプチュアルに考えたい場合なんかに、とても有用だと思 います。 イントロが弱いと良く言われるor自覚している人は、上記の点に意識して30報くらい、ざっと目を通すと流れが見えてくると思います。

Krest, Alexey Silakov, Jonathan Rittle, Timothy H. Yosca, Elizabeth L. Onderko, Julio C. Calixto & Michael T. Green Cytochrome P450 (P450) and chloroperoxidase (CPO) are both thiolate-ligated haem proteins that form a ferryl radical species called compound I. P450-I is, however, significantly more reactive than CPO-I. Variable-temperature Mössbauer and X-ray absorption measurements have now shown that increased electron donation from the axial thiolate ligand in P450-I may explain its greater propensity for C–H bond activation.

The Earth’s most abundant naturally occurring oxidant is—frankly—poorly understood and controlled, and thus underused. Copper-based enzyme metallocofactors are ubiquitous to the efficient consumption of dioxygen by all domains of life. Over the last several decades, we have joined many resear
