The vibrational spectrum of propyne-3d1
Priebe, H.,Nielsen, C. J.,Klaeboe, P.
, p. 1017 - 1020 (1980)
The i.r. spectra of propyne-3d1 in the vapour phase and as a crystalline solid at 90 K were recorded in the region 5000-200 cm-1.Raman spectra, including semiquantitative polarization data, of the vapour phase, of the neat liquid and of the solid at 90 K were obtained.The fundamental frequencies were assigned in good agreement with the result from a normal coordinate calculation.
Palladium-catalyzed annulation reactions for diastereoselective cyclopentene synthesis
Kohn, Benjamin L.,Jarvo, Elizabeth R.
supporting information; experimental part, p. 4858 - 4861 (2011/11/06)
Palladium-catalyzed annulation reactions of conjugate acceptors and allenyl boronic ester provide substituted cyclopentenes in high yields and, where applicable, diastereoselectivities. This method provides rapid assembly of building blocks for natural product synthesis, including polycyclic lactone and lactam products. Reactions are hypothesized to initiate by conjugate addition of a nucleophilic propargylpalladium complex.
