This section is concerned with the structure-properties relationships of 2,5-diarylsiloles and related compounds, including the substituent effects of 2,5-aryl groups, 3,4-substituents and 1,1-substituents on the silole rings. This fundamental study provides valuable information for the molecular design of new silole materials applicable to organic electronic devices. [Pg.654]

This procedure can be applied to the synthesis of a number of silole-containing n-conjugated compounds [2], Inter alia, the combination of the present cyclization with the Pd(0)-catalyzed crosscoupling reaction enables us to prepare a series of 2,5-diarylsiloles 6 in a one-pot manner from the diethynylsilanes (Scheme 2) [9,11],...

Thus, the intramolecular reductive cyclization of diethynylsilane, followed by quenching with the remaining lithium naphthalenide with a bulky chlorosilane and transmetalation with ZnCl2(tmen) (tmen = MAf.JVW -tetramethylethylenediamine), affords 2,5-dizinc silole 5, which is subsequently treated with the appropriate aryl bromides in the presence of a Pd catalyst to give the corresponding 2,5-diarylsiloles 6 in high yields.
