Pentakis(phenylethynyl)benzene and hexakis(phenylethynyl)benzene: A revision concerning two far too similar prototype hydrocarbons
Nierle, Jens,Barth, Dieter,Kuck, Dietmar
, p. 867 - 872 (2004)
A previously overlooked hydrodehalogenation reaction occurring during the multiple Pd0-catalysed C-C coupling reaction between phenylacetylene and hexaiodo- and hexabromobenzene was found to give pentakis(phenylethynyl)- benzene ( pentatolane ) as the major product, but no hexakis-(phenylethynyl)benzene ( hexatolane ) under conditions previously claimed to yield the latter hydrocarbon. As an alternative to a viable route to hexatolane described in the literature, an independent synthesis of this hydrocarbon through sixfold Sonogashira coupling of hexakis(ethynyl)-benzene with iodobenzene has been developed. Some physical and spectroscopic properties of hexatolane and of the hitherto unknown pentatolane have been determined after thorough purification by HPLC. Wiley-VCH Verlag GmbH & Co.

The Third-order Optical Non-linearity of the Phenylethynyl-substituted Benzene System
Kondo, Koichi,Yasuda, Sayo,Sakaguchi, Tohoru,Miya, Masaru
, p. 55 - 56 (1995)
Phenylethynyl substituted benzenes 1, 2 and 3 are synthesized by the Pd-coupling reaction of phenylacetylene with the corresponding bromobenzene; the third-order optical non-linearity (3)(ω)> increases with the participation of ?-conjugation
Multiple sonogashira reactions of polychlorinated molecules. Synthesis and photophysical properties of the first pentaalkynylpyridines
Ehlers, Peter,Neubauer, Antje,Lochbrunner, Stefan,Villinger, Alexander,Langer, Peter
supporting information; experimental part, p. 1618 - 1621 (2011/05/17)
Hitherto unknown pentaalkynylpyridines have been prepared in high yields by Sonogashira cross-coupling reactions of pentachloropyridine. Their photophysical properties were studied and compared to those of penta- and hexaalkynylbenzenes which were efficie
Palladium-Catalyzed Alkenylation and Alkynylation of Polyhaloarenes
Tao, Weijin,Nesbitt, Stephanie,Heck, Richard F.
, p. 63 - 69 (2007/10/02)
Alkenylation of several polyhaloarenes proceeded in low to moderate yields.Iodo groups could be reacted selectively in the presence of bromo groups; however, no more than two alkenyl groups could be introduced on contiguous, aromatic carbons.Alkynylation
