A palladium-catalyzed reductive cross-coupling of 1,3-dienes with boronicesters in which a pi-allyl Pd species is generated directly from a 1,3-diene via a Pd-catalyzed aerobicalcoholoxidation is reported. Both the scope of the process and the origin of a highly selective 1,2-addition are discussed.

Monoalkyl diazene species are versatile intermediates that have enabled many useful synthetic transformations in complex chemical environments. Herein we report the reductive transposition of 1,2-allenols for the direct synthesis of dienes through an alkene walk process.
