A simple TiCl4 promoted arylation of orthoformate and benzyl ethers by N,N-dialkylarylamines
摘要:
N,N-Dialkylarylamines react with trimethyl orthotormate and TiCl4 under ambient conditions to give the corresponding formyl derivatives in 75-89% yields, whereas the corresponding arylated products are obtained from benzyl ethers and acetals in 42-78% yields. (c) 2007 Published by Elsevier Ltd.

Photoconductive compositions comprising photoconductors and 1, 4, 5, 8-naphthalene bis-dicarboximide sensitizing compounds are disclosed. Compositions and elements containing such compounds are sensitized exclusively to radiation below 400 nm. Embodiments are disclosed in which the photoconductor is an arylalkane leuco base. Such embodiments are also nonpersistently conductive.
