A convenient method of the synthesis of gold NPs with low polydispersity is described. Triphosphinogold oxonium salt [O(AuPPh3)3]BF4 in the presence of amine and dioxygen is a versatile gold atom source in mesitylene. The amine takes part in the reduction of gold(I) atom precursor. Therefore in a 1/1 Au(I)/hexadecylamine stechiometry, "naked" gold nanoparticles are produced which precipitate within some minutes from the solution and form a gold mirror. Only an excess of amine enables the synthesis of ligand-protected nanoparticleswhich furthermore display a great tendency to self-organize. Solvent effect on the course of the reaction is discussed.

Air dried NPs contain morę carbon (31.66%) and hydrogen (4.55%) as would be expected from nitrogen (0.65%) content and was ascribe to some degree to the presence of mesitylene molecules.
