(Chemical Equation Presented) Axial and equatorial cyclohexylacyl and tetrahydropyranyl-2-acyl radicals gave distinct EPR spectra thanks to surprisingly large β-hydrogen atom hyperfine splittings that enabled them to be characterized and monitored. DFT computations indicated that the axial species (X = CH2) had a higher barrier to rotation about the (O)Cα-Cα bond. The computed difference ΔH° for the axial and equatorial radicals (R = H, X = CH2) was 0.8 kcal mol -1.
THE STEREOCHEMISTRY OF METAL CATALYSED HYDROGEN CYANIDE ADDITION TO ALKENES

Reaction of both terminal and cyclic alkenes have been shown to occur in a stereospecifically cis-manner with deuterium cyanide when a catalyst system based on Pd(DIOP)2 was used.Reactions of cyclohexene give only the products of equatorial cyanide incorporation.
