Substitution of 1,3,6,8-tetraethynylpyrene with sterically bulky trimethylsilyl groups enabled four modes of molecular packing, two polymorphs (triclinic system (Y-form) and “loose” crystal Colho (OK-form)), a ”rigid” liquid crystalline phase

A new synthetic protocol of 1-arylpropyne was developed by taking advantage of 1-(diphenylphosphoryl)propyne as propyne equivalent in Sonogashira coupling: consecutive subjection of phosphorylpropyne to t-BuOK and to aryl halides in the presence of P

The electronic effect of the Ph2P(O)-ethynyl group in Sonogashira couplings was investigated. Ph2P(O)-ethynylphenyl iodide showed higher reactivity than diiodobenzene because of the electron-withdrawing effect of the Ph2P(O) group. Copper acetylide,

Ph2P(O)-protected ethynes were successfully transformed to arylethynes in one-pot manner through t-BuOK-catalyzed deprotection followed by Sonogashira coupling with aryl halide. The arylethynes were obtained similarly by Ph2P(O)-deprotection, stannyl
