| 12 | γ-Butyrolactone Synthesis from Allylic Alcohols Using the CO_(2)Radical Anion显示文摘γ-Butyrolactone structures are commonly found in various natural products and serve as crucial building blocks in organic synthesis.Consequently,the development of methods for synthesizingγ-butyrolactones has garnered significant interest within the organic synthesis community.In this study,we present a direct and highly efficient approach for the synthesis ofγ-butyrolactones from allylic alcohols.Notably,this study represents the first instance ofγ-butyrolactone synthesis initiated by radical hydrocarboxylation using CO_(2)^(•–),generated from metal formates,followed by cyclization.This two-step process is achieved through the synergistic interaction of photoredox and hydrogen atom transfer(HAT)catalysis,resulting in the production ofγ-butyrolactones with exceptional efficiency.Additionally,when employingα,α-diaryl allylic alcohol derivatives as substrates,the reaction involves 1,2-aryl migration,which occurs concomitantly with CO_(2)^(•–)addition,leading to the formation of 4,5-substituted lactones in a good yield.The artificial force induced reaction(AFIR)method identified the preferred 1,2-aryl migration pathway along with potential byproduct pathways,in which the targeted 1,2-migration was found to be the most plausible pathway. | Saeesh R.Mangaonkar Hiroki Hayashi Wataru Kanna Suvankar Debbarma Yu Harabuchi Satoshi Maeda Tsuyoshi Mita | 2024 | Precision Chemistry2024，2，3： | 0 |
| 13 | 气体搅拌在钢包中无序混合的数值研究显示文摘流体混合在许多不同工业生产流程中,起到了非常重要作用。在现代化工业生产时代的今天,已经确定了一些典型工艺操作过程中的化学效率,这些化学效率与它们固有的流体性能有关。在炼钢领域,为了提高炼钢质量,通常采用喷吹气体方法促进钢水混合均匀。在钢包中吹入气体的方法几乎已被各钢厂广泛采用,在大包底部吹入气体时,气体在上升过程中可穿透液态钢水,有利于促进化学反应的进行,同时可均匀钢水化学成分和温度。 | Suvankar GANGULY | 2007 | 现代冶金(内蒙古)2007，，4： | 0 |
| 14 | 钢包吹气搅拌中气泡发生滑移现象的混合数值模拟研究显示文摘1引言
流体混合在各种不同的生产工艺中,起到了十分重要作用,在工业生产过程中,一些典型工艺操作的化学效率与它们固有的流体动力性能有关。为了在炼钢过程中,获得高质量的产品,现在几乎在每个炼钢车间中,都广泛采用浸入式气体喷吹方式作为钢包吹气工艺。从钢包底部喷吹的气体通过钢水上升到钢水表面,导致钢水自发混合,促进了钢水化学反应,因此,有助于钢包内的化学成分和温度均匀。除此之外,喷吹气体学有助于夹杂物的聚集和上浮。 | Suvankar GANGULY | 2008 | 现代冶金(内蒙古)2008，，2： | 0 |
