摘要：

Nickela-compounds with a five-membered ring, 4, are formed on Ni0 from CO2 and alkenes in the presence of the heterodifunctional ligand (cyclo-C6H11)2PCH2CH2-2-pyridyl (2). A ring contraction occurs on addition of a promotor, such as BeCl2, or on heating. The greater reactivity of the nickela-complex with a four-membered ring, 6, can be used in the former reactions with CO2, CO or CH2 = CH2. Such a sequence of reactions can be employed for the catalytic reaction of ethene with acrylic anilide on a (C6H11)3P/Ni0 system.
