Abstract

192) 1851 a Coupling reactions were run on a l-5-mmol scale with 2 mol% of tetrakis (triphenylphosphine) palladium (O). In reactions of triflate electrophiles, 3 equiv of lithium chloride was bed.* The yield is the overall yield of both steps when the enol ether was hydrolyzed directly to the ketone. oxy-1, 3-butadiene in 80% yield. Alkoxy 1, &dienes are versatile intermediates in organic synthesis. Andersson and Hallberg have already ...
