The Journal of organic chemistry, 72(19), 7431-7434 (2007-08-25)
The BF3.OEt2-catalyzed Friedel-Crafts propargylation of aromatic compounds with O-propargyl trichloroacetimidates is highly efficient and affords 1,3-diarylpropyne derivatives in good yields.
Fabien Goulay et al.
Physical chemistry chemical physics : PCCP, 9(31), 4291-4300 (2007-08-10)
The reactions of the ethynyl radical (C(2)H) with propyne and allene are studied at room temperature using an apparatus that combines the tunability of the vacuum ultraviolet radiation of the Advanced Light Source at Lawrence Berkeley National Laboratory with time-resolved

Magnetic resonance in chemistry : MRC, 45(8), 661-666 (2007-06-15)
Configurational assignment of five carbon, silicon and germanium containing propynal oximes has been carried out by means of experimental measurements and high-level ab initio calculations of their 13C-1H, 13C-13C and 15N-1H spin-spin coupling constants. The title compounds were shown to
