Abstract
Compounds of platinum (0) with aryl phosphines are stabilized by electron-withdrawing substituants. A maximum coordination number of three is observed in such cases, suggesting that platinum tetracarbonyl cannot be prepared. Compounds in which one phosphine is replaced by an aryl acetylene are also stabilized by electron withdrawal by the acetylene and quantitative data are given on the relative stabilities of these compounds. These data indicate that a two-coordinated diphosphine platinum (0) compound might be stable if an appropriate substituted phosphine is used. The effect of substituents on the stabilities of these compounds is discussed.Keywords
