“…The utility of polymer-supported palladium catalysts in this reaction has been explored. 110 2-Arylethylamines, an important moiety in many pharmacologically active molecules, can be synthesized via Heck reactions of acrylamide with iodobenzenes using a polymerbound palladium catalyst (Scheme 37). 111 The particular catalyst used for this example is obtained from poly(styryl)phenanthroline and palladium acetate.…”

The current interest in solid-phase organic synthesis has led to a renewed interest in a complementary technique in which solid supported reagents are used in solution phase chemistry. This technique obviates the need for attachment of the substrate to a solid-support, and enables the chemist to monitor the reactions using familiar analytical techniques. The purpose of this review is to increase awareness of the wide range of useful transformations which can be accomplished using solid-supported reagents.

“…Complex [15][16][17][18][19] An amount of 134 mg of PS-TPP, 22.4 mg of Pd(OAc) 2 , and 5 mL DMF (dried, nitrogen bubbled) were added to 20 mL glass vial with magnetic bar was closed with silicon septum and screw cap. The mass was stirred magnetically and heated to 45-50 °C for 4 h. The yellow product was precipitated.…”

Indirect reductive amination of aldehydes, catalyzed by polymer supported triphenylphosphine-palladium acetate complex PS-TPP-Pd(OAc) 2 catalyst have been developed. The imine is prepared with molecular sieves in the first stage, followed by reduction with potassium formate catalyzed by PS-TPP-Pd(OAc) 2 . The recovered catalyst could be reused for four consecutive cycles without loss in activity and provided an excellent yield of the desired products.

“…Zero-valent palladium complexes and nanoparticles are well known as efficient and selective catalysts for many organic reactions such as alkene arylation [5,6], cross-coupling [7], hydrogenation of dienes, ole�ns [8,9], and unsaturated alcohols [10]. Liquid phase catalytic hydrogenation of aromatic nitro compounds is widely used to produce corresponding amino derivatives, which are intermediates in the production of plastics, pharmaceuticals, and so forth.…”

A new approach to the synthesis of mixed-type immobilized catalysts by frontal polymerization of metal-containing monomer in the presence of highly dispersed mineral support has been developed. Synthesis of the acrylamide Pd(II) nitrate complex, Pd(CH 2 =CHCONH 2 ) 2 (NO 3 ) 2 (PdAAm), on the SiO 2 (Al 2 O 3 , C) surface and its consequent frontal polymerization and reduction lead to the formation of organic-inorganic composites with polymer-stabilized Pd nanoparticles. e immobilized metal complexes and palladium nanoparticles were characterized by various physical and chemical methods. e synthesized hybrid nanocomposites are efficient and selective catalysts for hydrogenation of cyclohexene, alkene, and acetylene alcohols, as well as diand trinitrotoluene. Catalyst intermediates separated by nondestructive testing method have been described and changing in the palladium charge during the catalytic process has been identi�ed.
