Silicon Compounds of 1,1-Bis(pyrrol-2-yl)ethenes: Molecular Structures and Chemical and Spectroscopic Properties

The first examples of silicon compounds of 1,1-bis­(pyrrol-2-yl)­ethenes have been synthesized via salt metathesis from a 2-fold lithiated dipyrromethene and different diorganodichlorosilanes (i.e., dimethyldichlorosilane, diphenyldichlorosilane, and 1,1-dichlorosilacyclobutane). Herein we report on their molecular structures, their optical properties, and some reactivity patterns.
