Chang, Sukbok Na, Youngim Choi, Eunjung Kim, Sunggak Catalytic and Highly Efficient 1,4-Addition of Terminal Alkynes to Conjugated Enones by [RuCl<sub>2</sub>(<i>p</i>-cymene)]<sub>2</sub>/Pyrrolidine A wide range of terminal alkynes was added to conjugated enones in a 1,4-fashion by a ruthenium catalyst in the presence of catalytic amounts of an amine base, and the corresponding γ,δ-alkynyl ketones were obtained in good to excellent yields. fashion;Catalytic;presence;Efficient;cymene;amine base;Terminal Alkynes;ketone;Pyrrolidine;alkynyl;ruthenium catalyst;yield;Conjugated Enones;RuCl 2;enone;terminal alkynes 2001-06-01
