Abstract

A series of 4-alkyl-1-bromosulfanylbenzenes having S-methyl 2, S-t-butyl 3, S-trityl 4, S-benzyl 5, and S-silylethoxymethyl 6 substituents were prepared and evaluated for their ability to form a monolayer consisting of an S-aryl adsorbate on Au (111) surface. The monolayer was formed via the selective hydrolytic removal of an alkyl group protecting the sulfur functionality upon adsorbtion onto the gold surface. Thiols having variable carbon chain length and a peripheral thiophene moiety 9, 10, 17, 18 and 23-26 were also prepared.

    These examples were chosen to illustrate the generality of our method. The physical and spectroscopic data for these S-t-butyl sulfides were identical to those observed in the literature.
