(Tetraphenylporphyrin)palladium was developed as a catalyst for the chemoselective and stereoselective hydrogenation of alkynes to cis-alkenes by the syn-addition of hydrogen. Alkynes containing various functional groups were tolerated in the reaction, which gave the corresponding cis-alkenes in good to excellent yields. Georg Thieme Verlag Stuttgart New York.

A range of amides fitted with (E) or (Z) disubstituted alkene groups were prepared and evaluated in intramolecular Kulinkovich-de Meijere reactions. The corresponding aminocyclopropanes were obtained with high diastereoselectivity. Good yields could be achieved with substrates bearing suitable substitutions at the olefin moieties.

3-Alkyn-1-ols as intermediate synthons in the preparation of some Lepidoteran sex pheromones were utilized.Characteristic fragmentations reflecting the position of the triple bond were found in the mass spectra of 3-alkyn-1-ols and alkyn-1-yl acetates in contrast to 1-tert-butoxy-alkynes.A partial isomerization of 1-tosyloxy-3-(Z)-octene to 1-bromo-3-(E)-octene within the reaction with NaBr in DMF was noticed by GC and 13C-n.m.r., for which a mechanism involving homoconjugation in an intermediate non-classical carbonium ion was suggested.
