SYNTHESIS OF A LIGNAN SKELETON VIA NICKEL- AND PALLADIUM-PHOSPHINE COMPLEX CATALYZED GRINGARD COUPLING REACTION OF HALOTHIOPHENES

Minato, Akio,Tamao, Kohei,Suzuki, Keizo,Makoto, Kumada

, p. 4017 - 4020 (1980)

A lignan skeleton is prepared in good yield through desulfurization of 3,4-dibenzylthiophene or 2,5-diaryl-3,4-dimethylthiophenes which are obtained by nickel- or palladium-phosphine complex catalyzed Gringard cross-coupling reaction of halothiophenes.
