The cations Zrans-[PtCl(CO)L2]+, where L = triethylor triphenylphosphine, have been synthesized according to the reactions:These platinum(II) cations are isoelectronic with [IrCl(CO)(Ph3P)2] and its rhodium(I) analog but are much less reactive, although the carbonyl group is readily displaced by Cl-. These syntheses allow reinterpretation of previous results1 on the reaction of frim-[PtHCl(Et3P)2] with C2F4 in the presence of Pyrex glass. The Zra«s-[PtCl(CO)(Et3P)2]+ cation is formed during this reaction, the counteranions being BF4-and the previously unknown SiF5ion, in this case stabilized products was not achieved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
