MOPs, which are typically synthesized by soft-templating synthetic approach, possess organic functionalities intact within their porous network that can anchor metallic species (catalytic groups). By using a soft-templating synthetic method, Chandra and Bhaumik synthesized two MOPs, denoted as mesoporous polytriallylamine MPTA-1 and MPTA-2 by using sodium lauryl sulfate and a mixture of sodium lauryl sulfate and Brij 35, respectively, as structure-directing agents (SDAs). 13). 119 The formation of Pd(0) from Pd(II) was confirmed by XRD, TEM, and UV-visible spectroscopy.
96 The resulting material is shown to be effective catalyst for the Heck reaction between n-butyl acrylate and aryl halides, yielding approximately 100% selectivity toward n-butyl-trans-cinnamate product at 90 ◦ C. Ionic Liquid-Stabilized Pd-NPs for the Heck Reaction (or Pd-NPCatalyzed Heck Reactions in Ionic Liquid Media). Ionic liquids can also be used as stabilizing agents for metallic nanoparticles for the Heck reaction. 97 Although the material showed significant Pd leaching, whose amount varied during the course of the reaction, it successfully catalyzed the Heck reaction between butyl acrylate and aryl iodides.
35, 36 Their supported forms are also commonly used as heterogeneous catalysts for the Heck reaction. 37–39 In addition, other metal oxides such as Al2 O3 , TiO2 , ZnO, ZrO2 , and MgO,40–42 and materials such as hydrotalcite43 and zeolites44 have also been successfully utilized as support materials for anchoring various palladium-based catalytic species for the Heck reaction. Moreover, organic-functionalized materials such as mesoporous organosilicas are shown to be very interesting support materials for making heterogeneous catalysts because their organic groups can serve as good anchor points to various metallic species such as organopalladium complexes and Pd nanoparticles (Pd-NPs).
