Primary and secondary amines react with 1,2-dihalo-4,5-dinitrobenzene to give nitro group substitution at mild temperatures. The halogen substituents on the ring remain unsubstituted and can be used for further reaction chemistry.

Site specifically functionalized dehydrobenzo[18]annulenes (DBAs) with previously inaccessible topologies (C2v and Cs symmetry) were prepared by utilizing an in situ protiodesilylation/alkynylation reaction. By application of a stepwise syntheticroute, donor and/or acceptor functional groups were introduced to the annulenic core in a designed manner. The electronic absorption spectra of the DBAs revealed
