Experimental thermochemical properties of benzene, toluene, and 63 polycyclic aromatic hydrocarbons, published within the period 1878–2008 (over 350 references), are reported. Available experimental data for enthalpies combustion used to calculate formation in condensed state, combined with sublimation, vaporization, fusion enthalpies, critically evaluated. Whenever possible, recommended values these gas state at T=298.15K provided.

Dibenzo-7-phosphanorbornadiene compounds, RPA (A = C14H10 or anthracene), are investigated as phosphinidene sources upon thermally induced (70-90 °C) anthracene elimination. Analysis of substituent effects reveals that π-donating dialkylamide groups paramount to successful transfer; poorer π-donors give reduced no transfer.

Eight new dinuclear gold(I) complexes, [Au2(L)X2] (1–8), were synthesized using a straightforward synthetic procedure under very mild conditions. The complexes have been characterized by NMR spectroscopy, elemental analysis, and single-crystal X-ray structure analysis. Their catalytic activity was investigated in the carboxylative cyclization of propargylamine (PPA). A superior performance comparison to [Au(IPr)Cl] (9) obtained for 1 2 having an eight-methylene bridge connecting two NHCs...
