摘要:
A series of 3,2'-polymethylene bridged 6-(2'-pyridyl)-2-phenylpyridines was prepared from benzo-fused cycloalkanone and beta-(dimethyl-amino) vinyl 2-pyridyl ketone as potential N,N,C-terdentates. Preparations and properties of their cycloplatinated complexes were described. Even highly distorted 3,2'-tetramethylene-6-(2 ''-pyridyl)-2-phenylpyridine can undergo cycloplatination.
