A novel metal-organic framework UiO-66-NH2-derived Br?nsted acid catalyst was synthesized on a gram scale by employing a postsynthetic modification strategy under mild conditions. The nanomorphology of the catalyst was designed and developed to enhance its catalytic performance. Acetalization and benzimidazole formation were evaluated to demonstrate the high reactivity and selectivity of the nanoscaled UiO-66-NH-RSO3H catalyst, which were found to be comparable to the reactivity and selectivity of the strong homogeneous Br?nsted acid catalyst. Furthermore, the UiO-66-NH-RSO3H catalyst was recycled several times without compromising the yield and selectivity.

Substituted bis(fur-2-yl), bis(fur-3-yl) and bis(thien-2-yl) maleimides with potential antidiabetic properties are described. Their synthesis involves, as a key step, a Suzuki cross-coupling between various boron derivatives and the diiodomaleimides. Therefore, a wide range of substituted symmetric and non-symmetric maleimide derivatives can be prepared.
