Allenyl ester precursors for 1H-inden-1-ol carboxylates: Comparisons with their propargylic equivalents having terminal alkyne functions
Asikainen, Martta,Woodward, Simon
experimental part, p. 5492 - 5497 (2012/09/08)
The reactivity of allenyl carboxylates, Ar(R1)CCCH(O 2CR2) and their isomeric equivalents the terminal propargylic carboxylates, ArC(R1)(O2CR2)CCH, in gold-catalyzed carbocyclization to ind
Dehydration-hydration of α-alkynols over zeolite catalyst. Selective synthesis of conjugated enynes and α,β-unsaturated ketones
Sartori, Giovanni,Pastorio, Andrea,Maggi, Raimondo,Bigi, Franca
, p. 8287 - 8296 (2007/10/03)
α-Alkynols 1 are convened in high yield and selectivity into conjugated enynes 2 or α,β-unsaturated ketones 3 by treatment with acid zeolites. The exclusive production of compounds 2 or 3 depends on the nature of the starting material 1 and experimental conditions.
Radical-Stabilization-Energy - the MMEVBH Force Field
Roth, Wolfgang R.,Staemmler, Volker,Neumann, Martin,Schmuck, Carsten
, p. 1061 - 1118 (2007/10/02)
Making use of the VB method of Malrieu et al. a force field has been developed, which allows to calculate heats of formation of hydrocarbons (conjugated and non-conjugated olefins, radicals and diradicals) with high accuracy.With this method radical stabilization energies (RSE) for a great number of delocalized radicals are calculated and compared with experimental values, derived from shock-tube measurements of dissociation energies or from rotational barriers of substituted olefins.A detailed analysis of the RSE with respect to structure, substituents, strain, and aromaticity is presented. - Key Words: Resonance energy / Heats of formation / Single pulse shock tube / Intrisic rotational barrier
DEHYDRATION OF TERITARY ARYL TRIMETHYLSILYL ACETYLENIC ALCOHOLS
Bychkova, N. A.,Zotchik, N. V.,Rubtsov, I. A.
, p. 1400 - 1404 (2007/10/02)
The dehydration of tertiary aryl acetylenic alcohols with a free and with a protected ethynyl hydrogen was investigated.The introduction of a trimethylsilyl protecting group leads to a considerable acceleration of the dehydration process and a rise in the
