  Direct and Selective Arylation of Tertiary Silanes with Rhodium Catalyst

  摘要：

  We have developed a convenient and efficient approach to the arylation of tertiary silanes under mild conditions. A variety of arylsilanes were synthesized in a one-step process with good to excellent yields in the presence of a rhodium catalyst with a base. The reaction was highly solvent dependent, and amides were the most effective of the various solvents used. This common catalyst system is highly tolerant of the various sensitive functional groups on the substrates, which might be difficult to extract by other methods. The rhodium-promoted silylation of aryl halides with electron-donating groups occurred more efficiently than the silylation of aryl halides substituted with electron-withdrawing groups. Heteroaromatic halides were also found to be readily silylated with tertiary silanes. The successful application of this reaction to the synthesis of a TAC-101 analogue, which is a trialkylsilyl-containing synthetic retinoid benzoic acid derivative with selective binding affinity for retinoic acid receptor-alpha, is also described.

  Scandium tris(o-aminobenzyl) complex Sc(o-CH2C6H4NMe2)3 (1) and its cationic derivative [Sc(o-CH2C6H4NMe2)2][B(C6F5)4] (2) catalyze the dehydrocoupling of alkoxyarenes with various aromatic hydrosilanes in toluene at 90 °C to give C-H silylation products in 15–89% yields (24 h). The product yield depends on the nature and the ratio of the substrates, and the new carbon-silicon bond is formed only in

  The silylation of ortho-functionalized aryl iodide with trialkylsilanes in the presence of RhCl(CO)(PPh3)(2) or [Rh(cod)(2)]BF4 and K3PO4 provides the corresponding arylalkylsilane in good to high yield. This catalytic system showed a dramatically different activity when Pd(t-Bu3P)(2) was used as a catalyst. (c) 2006 Elsevier Ltd. All rights reserved.
