Abstract
Pd-catalyzed reactions of butadiene, which proceed through a bis-π-allylpalladium intermediate,(η 3, η 3-C 8 H 12) Pd (2), were performed in the presence of both a pronucleophile (aceto-or cyanoacetate) and an electrophile (benzaldehyde). Methyl aceto- or cyanoacetate and benzaldehyde reacted independently with 2 to give telomers 8 and the divinyl-substituted pyranes 9, respectively. In the case of methyl cyanoacetate, the co- ...
