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
ALKINE UND CUMULENE-XX. TRIMETHYLSILYLALLENE DURCH RETRO-EN-SPALTUNG VON TRIMETHYLSILYLPROPARGYLETHERN
The trimethylsilylallenes 3a-f are obtained in excellent yields when thepropargylic precursors 2a-f are subjected to low pressure flow pyrolysis at ca. 620 deg C.
