2,2 -Bipyridines factors affecting yield

Some of the factors which affect the relative yields of 2,2 -bipyri-dine and of the organonickel complex are known. For example, the addition of about 1% pyrrole to the pyridine during the reaction causes a 60% increase in the yield of the complex and a 13% decrease in the amount of 2,2 -bipyridine formed (see Table III). When more pyrrole is present the yields of both products are lowered, but the ratio of complex to 2,2 -bipyridine is increased by a factor of about 7. These findings suggest that pyrrole can be incorporated into the complex, presumably by reaction between pyrrole and pyridine to...
