Abstract
Abstract Seven phenylpyrimidines have been cyclopalladated with lithium tetrachloropalladate and the products characterised by 1H and 13C NMR studies of their acetylacetonate complexes. 6-Methyl-2,4-diphenylpyrimidine and 2,4,6-triphenylpyrimidine undergo preferential metallation of the 2-phenyl ring. 4-(para-Nitrophenyl)-6-phenylpyrimidine is selectively monopalladated in the unsubstituted phenyl ring. 4,6-Diphenylpyrimidine has been doubly cyclopalladated, and an X-ray crystal structure of its acetylacetonate complex refined to an R value of 0.053.
