Electrochemistry of Organosilicon Compounds: From Halosilanes to Ethynylsilanes, Siloles, and Organosilicon Polymers
Electrolysis of various halosilanes such as iodo-, chloro-, and fluorosilanes in the presence of phenylacetylene on a Pt electrode leads to the formation of Si-sp-C bonds to give phenylethynylated products. Silole derivatives were synthesized from the electrolysis of bis(phenylethynyl)silanes thus obtained. The co-electrolysis of p-bis(chlorosilyl)benzenes and p-diethynylbenzenes afforded polymers composed of an alternating arrangement of p-bis(silanylene)phenylene and p-diethynylenephenylene units.
