Autor: Gilber R. Rosa, Glademir Alvarenga, Clarissa H. Rosa, Ana C. F. Goszczynski, Toni Jefferson Lopes, Jarrie P. Lima

Publikováno v: Environmental science and pollution research international. 27(22)

Liquid effluents from various dyeing industries often have a high concentration of dyes that diffuse into river systems and can be toxic and non-degradable in the environment. In this study, the potential of the use of timbauva seed husks in the prep

Coconut agro-industrial waste in the production of catalyst containing palladium: The report of a mini-project for teaching of sustainable Suzuki-Miyaura reaction

Autor: Diego S. Rosa, Gilber R. Rosa, Carla W. Scheeren, Clarissa H. Rosa, Fabio A. Duarte, Cristiane R. Schmitt, Toni Jefferson Lopes, Bruna P. Vargas, Fernanda Trombetta

Publikováno v: Journal of Cleaner Production. 185:342-346

A four-week mini-project for teaching is described for an experimental physical chemistry or organic chemistry course. The activities included synthesis of a Pd catalyst, PdCl2 supported on calcined coconut shell fiber, and its use in the preparation

On the Use of Calcined Agro-Industrial Waste as Palladium Supports in the Production of Eco-Friendly Catalysts: Rice Husks and Banana Peels Tested in the Suzuki–Miyaura Reaction

Autor: Diego S. Rosa, Clarissa H. Rosa, Gilber R. Rosa, Bruna P. Vargas, Manoel L. Martins, Marcia Victoria Silveira

Publikováno v: Waste and Biomass Valorization. 10:2285-2296

Two calcined agro-industrial wastes [rice husk ash (RHA) and banana peel ash (BPA)] with immobilized PdCl2 (Pd/RHA and Pd/BPA, respectively) that were produced at an extremely low cost were found to be efficient catalysts for Suzuki–Miyaura cross-c

Sulfamic acid: An efficient and recyclable catalyst for the regioselective hydrothiolation of terminal alkenes and alkynes with thiols

Autor: Maura L. Bruckchem Peixoto, Marcelo Gonçalves Montes D'Oca, Fábio Z. Galetto, Gilber R. Rosa, Clarissa H. Rosa, Benhur Godoi, Marcelo Godoi

Publikováno v: Tetrahedron Letters. 58:3777-3781

Herein, we described a new method for the preparation of thioethers through hydrothiolation of alkenes and alkynes, using sulfamic acid as a reusable catalyst. Generally, this new methodology afforded the desired products in very good yields, under m
