The mechanism of 4,4'-bipyridine-catalyzed diboration of pyrazines was studied by experimental observation of the inter-mediates and by theoretical calculations. Intermediary radical species were detected by ESR measurement of the reactions of 2,6-di

Acetylenedicarboxylates undergo trans-addition of tetraalkoxydiboron in THF at 60 °C in the presence of 4,4′-bipyridine (5 mol %) as a catalyst to give 2,3-diborylfumarates in good yields with high stereoselectivity.

A 4,4'-bipyridine-based catalyst system for diboration of pyrazine derivatives was established. The catalyst cycle consists of the following two steps: (1) reductive addition of the boron-boron bond of bis(pinacolato)diboron to 4,4'-bipyridine to for
