Green synthesis of nanostructured 1T/2H-MoS2 hybrid phase with polyol solvents and microwave heating
This study aims to investigate the effectiveness of the green microwave technique in producing 1T/2H-MoS2 nanomaterials using polyol solvents. The paper presents a thorough analysis of the structural and property characteristics of the synthesized materials and elucidates the underlying chemical mechanism that governs the formation of hybrid-phase nanostructures. Additionally, the role of polyol solvents in the practical synthesis of nano MoS2 under microwave heating is evaluated and explained.

The efficient synthesis of 12-substituted-3,4,4a,5,12,12a-hexahydrobenzo[b]acridine-1,6,11(2H)-triones starting from 2-amino-1,4-naphthoquinone, 1,3-cyclohexanedione, and different (hetero)aromatic aldehydes was developed. These reactions were carried out in acetic acid under microwave irradiation in the presence of p-toluenesulfonic acid as catalyst. The structure of the newly synthesized compounds were confirmed employing spectroscopic data as well as elemental analysis. The plausible mechanism of these three-component domino reactions was also described.

In this study, a green and practical approach towards Hantzsch dihydropyridine synthesis of acridine-1,8-diones is introduced. Via the mentioned protocol, the one-pot condensation reaction of structurally diverse aromatic aldehydes, dimedone and NH4OAc was promoted by microwave radiation at solvent and catalyst-free conditions.

Bài viết trình bày phản ứng Williamson tác chất và chất nền ở 2 pha khác nhau thực hiện theo tiêu chí hóa học xanh trong điều kiện không dung môi dưới sự chiếu xạ vi sóng kết hợp với xúc tác chuyển pha. Sự chiếu xạ vi sóng rất có hiệu quả trong phản ứng này do chất được dùng dưới dạng muối và xúc tác chuyển pha là những hợp chất phân cực nên hấp thu sóng rất mạnh.
