(η3-allyl)-ruthenium(II) complex [Ru(η3-2-C3H4Me)(CO)(dppf)][SbF6] is an efficient catalyst for the regioselective isomerization of terminal propargylic alcohols HCCCR1R2(OH) into α,β-unsaturatedaldehydes R1R2CCHCHO or ketones R3R4CC(R1)COMe (if R2=CHR3R4) under mild conditions. This complex has been also used as catalyst for the preparation of conjugated 1,3-enynes via dehydration of propargylic alcohols

Ring in the new: A new annulation for the efficient synthesis of substituted furans and pyrroles is reported. The RhIII‐catalyzed reaction of O‐methyl α,β‐unsaturatedoximes with aldehydes and N‐tosyl imines affords secondary alcohol and amine intermediates, respectively. Cyclization and aromatization occurs under the reaction conditions to provide access to biologically relevant furans and pyrroles
