A variety of functional aryl- and heteroarylchlorosilanes were prepared by
electrochemical reduction of halothiophenes, halofurans, halopyridines, and
substituted aryl halides in the presence of a large excess of commercial o
rganodi- or trichlorosilanes using an undivided cell, a sacrificial Mg or A
l anode, a constant current density, and tetrabutylammonium bromide as the
supporting electrolyte. New structures are described, and some examples of
the use of these more elaborate chlorosilanes are given, particularly as in
teresting precursors for the preparation of polarized D-A and D-D organosil
icon models.
