Shaqada hadda jirta waxay ka warramaysaa hal tallaabo oo cusub, borotokoolka cagaarka ah ee isku-dhafka palladium nanoparticles (PdNPs) ee istaarijka-dejiyey ee leh dhexroorka walxaha celcelis ahaan 30-40 nm.Qaybahani waxay ahaayeen kuwo deggan oo lebbisan cabbir ahaan.Hab-maamuuska hadda jira, hoos u dhigista tamarta qoraxda ee la isku koobay ee palladium chloride ayaa lagu gaarey iyadoo la isticmaalayo citric acid wakiil yaraynta iyo istaarijka sida wakiilka koofida.UV-muuqaal spectroscopy, gudbinta Electron mikroskoob, Goobta Siideynta Gun-Scanning Electron mikroskoobyo, Aagga la doortay Electron Diffraction iyo Electron kala firdhiso raajada farsamooyinka falanqaynta Spectral ayaa la isticmaalay si loo garto istaarijkan daboolay PdNPs.Halkan;waxaanu ka warbixinaynaa isku darka istaarijka iyo citric acid ee isku-dhafka PdNP-yada markii ugu horeysay.Dhaqdhaqaaqa catalytic ee nanoparticles la farsameeyey ayaa lagu hubiyay falcelinta isku-xidhka Suzuki iyo Heck.Wax-soo-saarka badeecada waxa xaqiijiyay GC.Alaabooyinka waxaa lagu xaqiijiyay iyadoo la adeegsanayo falanqaynta GC-MS iyo sidoo kale iyadoo la adeegsanayo GC oo leh he lp ee heerarka dhabta ah.Tamarta qorraxda ee caawisay istaarijka xasiloon ee PdNPs waxay muujisay firfircooni aad u wanaagsan samaynta curaarta CC ee u dhaxaysa aryl halides (I, Br) oo leh phenyl boronic acid iyo ka-soo-saarkeeda.Intaa waxaa dheer, kicinta ayaa muujisay firfircooni wanaagsan ee falcelinta isku xidhka Heck ee samaynta dammaanadda CC ee aryl halides oo leh alkene caraf udgoon.Isticmaalka istaarijka, citric acid, biyaha iyo tamarta qoraxda ayaa ka dhigaysa borotokoolka hadda mid cagaar ah.
