An investigation aimed at devising a procedure for preparing alkyl-or aryl-capped iron sulfide particles continues. An initial attempt to prepare fine-particle, aryl-capped iron sulfides (S-31) involved the competitive reaction of thiophenol (PhSH) and sodium sulfide (Na{sub 2}S) with Fe(II). However, SEM examination of the particles formed by this procedure indicated that no size control had been attained. It was thought that the phenyl group of thiophenol was not bulky enough to prevent thiolate bridging and consequent particle size growth of the metal sulfide. So the bulkier thiol 1-adamantanethiol was synthesized and used in synthesis S-33 in the next attempt to prepare fine-particle, capped iron sulfides.
