摘要

Abstract 1-(Triisopropylsilyl)-3, 4-dichloropyrrole and 1-(triisopropylsilyl)-3, 4-difluoropyrrole were conveniently prepared from the corresponding 3, 4-dibromopyrrole by lithiation followed by halogenation. 2, 3, 17, 18-Tetrahalogeno [26]-and [28] hexaphyrins have been prepared by condensation of 3, 4-dihalopyrroles and a dipyrromethane-dicarbinol. 2, 3, 17, 18-Tetrahalogenated hexaphyrins display variable structural and electronic properties ...
