摘要

Abstract Oxindole derivatives have been obtained from N-alkenyl-o-chloroanilides by reaction with tetrakis (triphenylphosphine) nickel (0) in toluene as solvent in good yields. A detailed analysis of all the products of the reaction allows to confirm the postulated mechanism of the cyclization reaction. The o-chloroanilides of the 3-cyclohexenylacetic acid fails in the cyclization reaction, since the torsional hindrance seems to avoid that the ...
