Tetraarylethylenes from Diarylmethanones and Hexachlorodisilane: The “Sila-McMurry” Reaction

Hexachlorodisilane reacts with diarylmethanones (aryl=C6H5, 4-MeC6H4, 4-tBuC6H4, 4-ClC6H4, 4-BrC6H4) to furnish the corresponding tetraarylethylenes in good yields. The reductive conversion requires temperatures of about 160 °C and reaction times of 60–72 h. In the initial step, the Lewis-basic carbonyl groups likely generate low-valent [SiCl2] as an analogue of [TiCl2] in the classical McMurry reaction. The coupling sequence further proceeds via benzopinacolones, which have been isolated as key intermediates.

Synthesis and electroluminescent properties of fully substituted ethylene moieties

We synthesized a new bluish-green emitting material using fully substituted ethylene moieties, 1,1,2,2-tetrakis(4-tert-butyl-phenyl)ethene [TBPE] and 1,1,2,2-tetrakis(4-tert-butyl-biphenyl)ethene [TBBPE] by McMurry reaction. These products were identified
