摘要

In the presence of palladium (0) catalyst, propargylic electrophiles undergo carbon-carbon bond formation with organometallic compounds predominantly at the allenyl This is because the propargylic electrophiles employed in these reactions tend to form an allenylpalladium intermediate by oxidative addition. In contrast, there is no report on catalytic reactions of propargyl electrophiles proceeding via a propargyl palladium intermediate exclusively. ...
