Abstract
Abstract 4-tert-Butylpyridine has been shown to be a beneficial additive in the Ni(II)/Cr(II)-mediated coupling reaction. This additive allows for homogeneous reactions, improves reproducibility, and inhibits homo-coupling of vinyl iodides or triflates. Improved workup procedures using chromium ion chelators (ethylenediamine or sodium or potassium serinate) allow for a better mass recovery . © 1997 Elsevier Science Ltd.
