摘要：

The use of pendant pyrazole groups to induce double cyclopalladation of 2-phenylpyrimidines has been investigated 4,6-Bis(pyrazol-1-yl)-2-phenylpyrimidine undergoes monocyclopalladation only, whilst 4-methyl-2-phenyl-6-(pyrazol-1-ylmethyl)pyrimidine reacts preferentially to give the cyclopalladated regioisomer in which the ligand exhibits tridentate coordination. 4,6-Bis(pyrazol-1-ylmethyl)-2-phenylpyrimidine gives a mixture of singly and doubly cyclopalladated products. © 1990.
