Background: High-pressure chemistry offers the possibility to have faster and cleaner transformations thus addressing most of the green chemistry principles. Among the devices recently developed, Q-tube is worth mentioning since it is cheap, easy to handle, safe and highly versatile. Methods: The most recent and interesting results obtained using such technique are reviewed in this study. Results: Examples of the Q-tube assisted reactions in organic synthesis are presented in a critical manner making where possible, a comparison with conventional heating strategies and unconventional energy source such as microwave or ultrasounds assisted synthesis. The application of Q-tube pressure reactor in biofuels manufacture is also discussed. Conclusion: The literature survey clearly revealed that Q-tube is a valid tool in organic synthesis.

A Q-tube assisted, efficient method for the preparation of 2-phenylquinazolin-4-ones is here presented. The target structures were prepared through the one-pot, multicomponent reaction between isatoic anhydride, an aromatic aldehyde and a primary amine following a catalyst-free approach. The use of the commercially available Q-tube© apparatus allowed to perform reactions at external temperature higher to the solvent boiling point generating medium pressure conditions, shortening the reaction times and affording good yields in all the example herein reported.

This manuscript aims to be a celebrative tribute to the 200 th anniversary of "selenium birthday" presenting an overview of the contribute of our group in different fields of this research, ranging from the development of new reagents for green chemistry and catalysis to the design and synthesis of novel molecules as anti-HIV and, as recently reported by others, antimicrobial agents. We are strongly convinced that in the next future important discoveries could emerge as a result of a research that produces thousands of new publications every year. In the form of prospective article here we just collect selected results among those presented by our young students at 6 th Workshop of the SeSRedCat Network which was held in Wroclaw, Poland (21 th 23 rd September 2017) Selenium (Se) was named by J. J. Berzelius exactly 200 years ago after its discovery in the residue of sulfuric acid preparations from a mining operation. At the beginning Berzelius believed to have in his hands a sample of Tellurium (discovered some years before) and only at the beginning of 1818 further investigations on the redox properties demonstrated that it was a new element and the name Selenium

The interaction between N,N-dimethyl-selenobenzoamide PhC(=Se)NMe2 (1) and various Lewis acids of different strength, namely IC6F13(I), B(C6F5)3 (B) and Me+, has been analysed here by a combined experimental and theoretical approach....
