Protection (and Deprotection) of Functional Groups in Organic Synthesis by Heterogeneous Catalysis

SiO2@FeSO4 NANO COMPOSITE AS NANOCATALYST FOR THE GREEN SYNTHESIS 1,1-DIACETATES FROM ALDEHYDES UNDER SOLVENT-FREE CONDITIONS

“…2,3 In organic reaction protection of functional groups during synthesis compounds are essential. 4 One of the important functional groups is aldehydes, because of easy converted to other organic groups for examples, alcohol, 5 carboxylic acids, 6 aldoximes. 7 moreover, the diacetates of α,β-unsaturated aldehydes serve as an important precursor for Diels-Alder reactions.…”

Alumina sulfuric acid (ASA), tungstate sulfuric acid (TSA), molybdate sulfuric acid (MSA) and xanthan sulfuric acid (XSA) as solid and heterogeneous catalysts in green organic synthesis: a review

“…Also, wastages and by-products can be minimized. [20][21][22][23] Development of novel heterogeneous catalysts to facilitate various organic transformations is an intense area of research in recent years. Therefore, many efforts have been made by scientists constantly to introduce new and novel heterogeneous catalyzed organic synthesis by using alumina sulfuric acid (ASA), tungstate sulfuric acid (TSA), molybdate sulfuric acid (MSA) and xanthan sulfuric acid (XSA) (Figure 1), which are more efficient, economical and compatible with the environment.…”

Determinação Da Energia De Ativação Na Produção De Acetato De Eugenila via Catálise Heterogênea

“…Aspectos ambientais e econômicos tem despertado crescente interesse, tanto da comunidade acadêmica quanto industrial em pesquisas buscando a elaboração de processos que sejam ambientalmente favoráveis, seletivos, apresentem elevados rendimentos e fácil manipulação (Sartori et al, 2004). Dentre esses fatores, se destaca a seleção do catalisador que deve ser realizada de acordo com a reação envolvida e o produto requerido, estes devem apresentar como uma das principais características baixa energia de ativação (Dumesic;Huber;Boudart, 2008).…”
