A practical and highly site-selective copper-PhBPE-catalyst-controlled allenylation with propargyl boronates has been developed. The methodology has shown to be tolerant of diverse ketones and aldehydes providing the allenyl adducts in high selectivity. T

Chemical Equation Presented The utility of allenyl and propargyl boronates for the propargylation of aldehydes and ketones mediated by zinc is presented. The reaction is catalytic in zinc with allenyl or propargyl borolanes. The propargylation with crystalline and air-stable propargyl diethanolamine boronates was also achieved. A catalytic cycle is proposed, and preliminary mechanistic studies are discussed.
