Amine-tetrachloromethane charge transfer complexes: a structural and computational study

摘要

Amine-tetrachloromethane charge-transfer complexes have recently been shown to be useful intermediates in transition-metal free solar light-assisted organic synthetic chemistry. Of particular promise is the complex of 1,4-diazabicyclo[2.2.2]octane (DABCO) which may serve as a starting point for several potential reactions involving oxidation of organic compounds. Here we disclose the crystal structure of the [DABCO center dot center dot center dot CCl4] complex, and computational studies of two possible complex structures in their ground state, as well as in their first singlet and first triplet excited states.
