Does anyone have good reliable syntheses for preparing both the cis- and trans- complexes of a square planar metal with the same ligands that I could use in the teaching lab?
I had 2 students try to make cis- and trans-platin this year, which you think would be easy, but the data are inconclusive. I would especially like a prep that involves phosphines with different phosphorus environments so that I could show them cis/trans coupling constants. But maybe not in the same experiment.
Basically, this is a plea from an early metal chemist for some help finding bulletproof late metal preps.
