Resumen

The addition of different nucleophilic compounds (aliphatic and aromatic alcohols, thiols and phosphines) to alkynylalkoxycarbene complexes has been studied. The reaction with smaller nucleophiles proceeds readily and regioselectively at the β-carbene position. With more substituted nucleophiles the reaction rate slowed down considerably. Addition of a catalytic amount of DBU (1,8-di-azabicyclo[5.4.0]undec-7-ene]) speeded up the reaction and improved the E/Z ratio. © 1992.
