On October 15, 2007, Ju-Nam, Yon; Allen, David W.; Gardiner, Philip H. E.; Light, Mark E.; Hursthouse, Michael B.; Bricklebank, Neil published an article.Reference of (6-Bromohexyl)triphenylphosphonium bromide The title of the article was The synthesis and characterisation of masked phosphonioalkyl selenolates: Potential ligands for the production of functionalised gold nanoparticles. And the article contained the following:
Two new masked phosphonioalkylselenolate ligands, bis(3-triphenylphosphoniopropyl) diselenide- and [6-(selenocyanato)hexyl]triphenylphosphonium selenocyanates, were prepared The mol. structure of the bis(3-triphenylphosphoniopropyl) diselenide diselenocyanate was determined by x-ray crystallog. The structure reveals an overall stoichiometry of {[Ph3P+(CH2)3Se]2(SeCN-)2·KOH}, with the bis(3-triphenylphosphoniopropylselenium) diselenocyanate units arranged in pairs around an inversion center. The K ion is disordered over several positions but its main component forms a near linear K···Se contact to one of the Se atoms in the diselenide bond. The hexyl derivative, [6-(selenocyanato)hexyl]triphenylphosphonium selenocyanate forms as a yellow oil that was characterized spectroscopically. Both phosphonioalkylselenide cations undergo reductive cleavage to form phosphonioalkylselenolate zwitterions. Attempts to prepare phosphonioalkylselenolate-functionalized Au nanoparticles in situ through the NaBH4-promoted reduction of tetrachloroaurate salts in a H2O/CH2Cl2 biphasic system gave colloidal gold. The experimental process involved the reaction of (6-Bromohexyl)triphenylphosphonium bromide(cas: 83152-22-1).Reference of (6-Bromohexyl)triphenylphosphonium bromide
