摘要:
Efficient syntheses and characterization of-a platinum metallacyclyne containing one cyclic enyne pocket (3), the first dinuclear platinum metallacyclyne containing two cyclic enyne pockets (4), and 2,2',6,6'-tetraethynyltolan (2) are reported. Syntheses of 3 and 4 employ bidentate phosphines or cis-platinum starting materials and high dilution techniques to effect high yields.
