Abstract

In the context of sustainable development, efforts have to be done to produce chemicals and materials by taking into account environmental constrains. Particularly, catalysis has an important role to play, because it enables to achieve reactions with higher rates and higher selectivity’s in the desire products. The development of new strategies for recycling catalysts that reduce the consumption of additional substances for recovering and purification of the catalyst can result a considerable economic and ecological benefits. Immobilization of catalytic functionality into inorganic matrix is of great interest in organic synthesis and green chemistry not only for their high selectivity and high yields, but also for their advantageous heterogeneity, reusability and positive environmental impact. In this context, this mini review provides a brief overview of pores functionalized mesoporous silica materials synthesized by assisted self-assembly process “soft way”, which consists of the hydrolysis and polycondensation of silylated molecular precursors in the presence of surfactant which plays the role of structure-directing agent. After a brief rappel of the design and functionalization of mesostructured silica, the accessibly and the distribution of the organic moieties in the pores surface will be demonstrated trough specific chemical modifications. Finally, several type of pores functionalized materials that act as organocatalysts will be described as well their catalytic activities in metathesis, aldolisation, epoxydation will be discussed.
