Regiocontrolled synthesis of ethene-bridged para-phenylene oligomers based on PtII- And RuII-catalyzed aromatization

We report the regiocontrolled syntheses of ethene-bridged paraphenylene oligomers in three distinct classes by using PtII- and Ru II-catalyzed aromatization. This synthetic approach has been developed based on twofold aromatization of the 1-aryl-2-alkynylbenzene functionality, which proceeds by distinct regioselectivity for platinum and ruthenium catalysts. Variable-temperature NMR spectra provide evi-dence that large arrays of these oligomers are prone to twist from planarity. The UV/Vis and photoluminescence (PL) spectra as well as the band gaps of these regularly growing arrays show a pattern of extensive π conjugation with increasing array sizes, except for in one instance.

Synthesis and photocyclization of macrocyclic stilbene derivatives

The stereoselectivity of the formation of macrocyclic stilbenes as well as the regioselectivity of their photocyclization are strongly influenced by the length of the connecting alkanediyl chain. The stereoisomers of the macrocyclic stilbenes and the corr

Oxygenated phenanthrenes via quinol ketals: Cyclization vs. migration

2-methoxyphenanthrenes were prepared by reaction of lithiated 2-bromostyrenes with quinone monoketals followed by acid-mediated cyclization of the resulting p-arylquinol ketals. Substitution at the bromostyrene side-chain or the quinone monoketal ring had only a modest effect on yields, but oxygen substitution on the bromostyrene aromatic nucleus resulted in a competing 1,2-aryl migration arising during the quinol ketal cyclization step. The extent of this rearrangement was found to be a function of the Lewis acid/solvent system employed.

Oxygen Sensitization of Electron Capture Response to Isomers of Polycyclic Aromatic Amines and Hydroxides

The use of the oxygen-sensitized constant-current electron capture detector (ECD) with gas chromatography for analyte identification is extended by examining the responses of numerous polycyclic aromatic amines and hydroxides where an appropriate EC-enhancing chemical tag has been attached to the amino group or the hydroxy group has been methylated.For the majority of isomeric groups examined, measured response enhancements of the derivatives are sufficiently dependent on structural differences as to provide an additional means by which substitution isomers can be differentiated.The ion chemistry responsible for the EC and oxygen-sensitized responses also has been examined by the use of an atmospheric pressure ionization mass spectrometer (APIMS).
