Estudos mecanísticos de reações de cicloadição e ciclização através de ferramentas experimentais e teóricas
(Universidade Federal de São Carlos, 2022-02-22)
Part 1: The 1,3-dipolar cycloaddition of nitroolefin and azides have emerged as an important approach for the synthesis of 1,2,3-triazole. We describe the rationalization of the regioselectivity/reactivity trends of this ...
Funcionalização de 5-iodo-1,2,3-triazóis e síntese de seleno- e tioésteres por meio de reações de acoplamento carbonilativo empregando monóxido de carbono gerado ex situ
(Universidade Federal de São Carlos, 2022-06-06)
The use of pressurized carbon monoxide (CO) gas cylinders can lead to serious risks during their handling. Hence, the demand for safer carbonylation methods has been gradually increasing with the use of different techniques ...
Parametrização de ligantes em Co(salen) aplicados na despolimerização de ligninas
(Universidade Federal de São Carlos, 2022-05-26)
Since the industrial revolution, fossil sources such as oil, natural gas or coal have become indispensable resources for human development with a variety of uses: from energy generation to drugs production and household ...
Reações de fotooxigenação de pinenos em pinocarvonas, trans-pinocarveóis e mirtenal: uma abordagem em regime de fluxo contínuo
(Universidade Federal de São Carlos, 2022-04-18)
In this work, a continuous flow protocol to prepare (-)-pinocarvone, (-)-trans-
pinocarveol and (+)-myrtenal from (+)--pinene, (-)--pinene and -pinene through
photooxygenation reactions was described. Furthermore, ...
Arilsulfonilação tri componente de diidrofurano e ésteres vinílicos via catálise dual níquel/fotorredox
(Universidade Federal de São Carlos, 2022-03-29)
The pursuit of synthetic protocols aligned to sustainability goals, increasingly necessary in the global context in which we operate, caused a great effort by synthetic chemists to develop photocatalytic methodologies ...
