The synthesis of allenes by Cu(i)-catalyzed regio- and stereoselective reduction of propargylic carbonates with hydrosilanes
Cu(i)-catalyzed anti-SN2′-type reduction of internal propargylic carbonates with hydrosilanes affords various di- and trisubstituted allenes with high regioselectivities; the reactions are compatible with functional groups and work efficiently
Generation of allenic/propargylic zirconium complexes and subsequent cross-coupling reactions: A facile synthesis of multisubstituted allenes
(Chemical Equation Presented) The β-alkoxide elimination reaction of propargylic ether with Negishi reagent leads to allenes and/or alkynes after hydrolysis. The product distribution is highly dependent on the substitution pattern of starting propargylic
