Abstract
A regioselective transition metal mediated domino reaction of carbon nucleo philes with oxalic acid-bis(imidoyl)chlorides is reported. This reaction pr ovides a convenient access to E-configured 5-ylidenepyrrol-2(5H)-ones. With out the presence of cobalt(II) or nickel(II) salts, open-chained products w ere obtained. The regioselective cyclization is controlled by the coordinat ion of the nitrogen atoms of the 1,4-diazadiene system to the transition me tal.
