180 Hydrogenation of DehydrolinaloolCH 2~0.5 nmFigure 3. The structure of HPSHPS was developed by the Laboratory of Sorption Processes (INEOS RAS). Itwas synthesized by the introduction of methylene bridges between neighboringphenyl rings of linear polystyrene, thus the porous structure was obtained.Preparation of palladium nanoparticles occurred by the adsorption of freshlyprepared Na 2 [PdCl 4 ] solution (Na 2 [PdCl 4 ] is hydrolyzed in time) into the HPSmatrix. The reduction of palladium compound by hydrogen led to the formation ofpalladium nanoparticles.Catalysts on the Basis of Polyelectrolytes.Formation of metal nanoparticles in ultra thin polyelectrolyte systems was carriedout using polydiallyldimethyl ammonium chloride (PDADMAC) by the “layer-bylayer”deposition method. PDADMAC was purchased from Aldrich (Mw = 400 000– 500 000). The structure of PDADMAC is shown in Fig. 4.+ -N ClH 3 C CH 3 nFigure 4. The structure of PDADMACCatalyticTests.Catalytic reactions were carried out in the isothermal glass batch reactor installed ina shaker and connected to a gasometrical burette. The reactor was equipped with twoinlets: one for catalyst, solvent, and substrate, and one for hydrogen feeding. Thetotal volume of fluid phase is 32 mL. Hydrogen consumption was controlled by
