29 - 020Intramolecular Propargyl Transfer Reaction Catalyzed by Elec-trogenerated Nickel Complexes. — 2-Propargyloxy benzaldehydesundergo nickel-catalyzed electrochemical propargyl transfer reaction to give2-hydroxyphenyl-substituted homopropargyl alcohols together with productsresulting from cleavage of the ether bond. In addition, allene isomers are formedfrom (IV) and (VII). Analogous propargyl transfer from a meta position [cf.(X)] does not occur, suggesting an intramolecular mechanism. — (FRANCO,DELPHINE; DUNACH, ELISABET; Tetrahedron Lett. 40 (1999) 15, 2951-2954; Lab.
