摘要：

In this report we present a direct synthesis of bromo 8 and iodo 9 trisubstituted tribenzosilatranes. Cornmercially available o-anisidine I was transformed into the triarylamine 3 in a two-step sequence. which was halogenated to furnish;h the tribromo 4 or the triiodo 5 substituted triamines, respectively. Subsequent deprotection of the methyl ethers furnished the novel tripod ligands 6 and 7. A transilylation reaction in the last step led to the synthesis of the desired para-halogenated tribenzosilatrane 8 and 9. (C) 2004 Elsevier Ltd. All rights reserved.
