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.

PtCl2-catalyzed hydrative cyclization of trialkyne functionalities to form bicyclic spiro ketones

(Chemical Equation Presented) Triple rounds: A regioselective hydrative cyclization of triynes has been developed to give bicyclic β-hydroxy spiro ketones, which undergo subsequent dehydration to give the β,γ- unsaturated ketones (see scheme). Model reactions suggest that this platinum catalysis includes two selective hydrations, an alkyne insertion, and an aldol condensation.
