Benzene-derived carbon nanothreads

Nature Materials, 2014
Low-dimensional carbon nanomaterials such as fullerenes, nanotubes, graphene and diamondoids have extraordinary physical and chemical properties. Compression-induced polymerization of aromatic molecules could provide a viable synthetic route to ordered carbon nanomaterials, but despite almost a century of study this approach has produced only amorphous

Benzene and its Derivatives-II

1982
The electrophilic substitution reactions of benzene have been described in the previous chapter. Two additional reactions of benzene are covered in this chapter. The rest of the chapter is devoted to the reactions of benzene derivatives, having electron-withdrawing substituents on the ring.

Simple Benzene Derivatives

1955
Phenols, i. e., aromatic compounds with hydroxyl groups directly attached to the nucleus, are widely distributed in plants. Many naturally occurring phenols contain, in addition, other functional groups attached directly to the nucleus or to side chains, e. g. —COOH, —COOR, —CHO, alcoholic —OH, etc.

Temporary negative ion resonances in benzene and benzene derivatives

Physics Letters, 1966
Abstract New, intense, energy loss resonances below the first excitation potential were discovered in the electron impact excitation spectra of benzene and six of its derivatives. The observed resonances for o-C6H4CH3Cl, C6H5Cl, C6H5Br and o-6H4Cl2 peak at exactly the same energy as the dissociative electron capture resonances previously reported for

Anodic fluoroalkylation of benzene derivatives

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1978
1. A new electrochemical reaction was discovered, namely the anodic trifluoromethylation of substituted benzenes by trifluoroacetic acid. 2. It was shown that the mechanism of the anodic process in the system CF3COOH-aromatic compound changes when acetonitrile is added to the system.

Volatile Benzene Derivatives as Honey Biomarkers

Synlett, 2013
The biodiversity of low-molecular-weight volatile benzene derivatives has been a driving force for the discovery of specific or nonspecific biomarkers that can be used to determine the botanical origin of honey. Stimulated by the challenge of their structure identification and by the possibility of developing fingerprinting methods, exploratory studies
