Synthesis and reactivity of palladium and platinum carbenes

Literature Discussion

Submitted by Chip Nataro, Lafayette College

The literature discussion is based on a paper (Organometallics ASAP) in which the synthesis and reactivity of a palladium and platinum carbene compound. The palladium and platinum compounds exhibit some interesting differences that show up throughout the paper. There is a lot of detail in the experimental section so this paper seems longer than it actually is for the purposes of having students read it. The authors do a good job of going through the rationale of the work that was done and students should be able to follow along. There is a large amount of spectroscopic data in the paper and a nice presentation of coupling to spin 1/2 nuclei that is less than 100% naturally abundant.

File Questions for students18.1 KB
Learning Goals: 

Upon completing this LO students should be able to 

  1. Use the CBC method to count electrons in the compounds in this paper
  2. Describe the bonding in carbene compounds presented in this paper
  3. Present a rationale for the differences in the reactivity of related palladium and platinum compounds
  4. Formulate reaction mechanisms for the compounds in this paper
  5. Explain 195Pt satellites
Implementation Notes: 

Students should read the paper before coming to class. Although there are a lot of questions in the LO, if the students have done a good job reading the paper I would anticipate that they can get through them all. Certainly some of the questions can be left out, or perhaps only provide the students with a few of them before class, in particular the students should be able to do electron counts before class.

Time Required: 
50 minutes or so
Evaluation Methods: 

This paper was presented late in the fall semester and as such I was unable to use it in class. I look forward to using it in the fall.
