The modulation of reaction conditions during nanoparhcle synthesis plays a significant role in controlling particle size and shape. Obare and coworkers investigated the effects of reaction temperature and reaction time on the pyrolysis of [Pd3(OAc)e] to form thioether-stabiUzed Pd nanopartides [48]. Both conditions were found to have a profound influence on nanoparhcle size, as well as size distribution. A 1 h period of pyrolysis of a toluene soluhon containing a 1 5 raho of [Pd3(OAc)6] to n-dodecyl sulfide was carried out at temperatures of 95, 100, 110,... 

Figure 9.26 UV-visible absorbance spectra of [Pd3(OAc)6] and n-dodecyl sulfide in a 1 5 molar ratio, respectively, dissolved in toluene. As the temperature is raised from room temperature to 95 °C, Pd nanoparticles begin to form, and the color of the solution changes from yellow to dark brown. At SOX, the solution color Is dark brown, indicating the formation of Pd nanoparticles, (a) Omin ...

Model reactions showed that 2-dodecyl-5-methyl thiophene, benzo[b]thiophene, 2-n-butyl benzo[b]thiophene and dibenzothiophene were unaffected by these reaction conditions after a 4-hour reflux. For the LiAlH4 reduction step the solvent dioxane (b.p. 100°C) is preferred to either diethyl ether or tetrahydrofuran since preferential reduction of certain sulfides in the latter solvents has been observed (2). The results of the sulfide analyses for several petroleums from Alberta are summarized in Table I.
