My Notes

This literature discussion LO was created for the ACS National Award Winners 2024 collection. Dr. Herbert Roesky was the recipient of the 2024 Frederic Stanley Kipping Award in Silicon Chemistry. This LO is based on the article "Lewis Base Stabilized Dichlorosilylene" published in Angewandte Chemie 2009, 121, 5793-5796. DOI: 10.1002/ange.200901766.

guiding questions for students 23.48 KB
Learning Goals

After reading the article and answering the guiding questions, students will be able to....

1) Compare and contrast ligand-stabilized SiCl2(silylene) to SiCl4 and non-coordinated SiCl2.

2) Draw Lewis structures and identify different oxidation states of compounds containing Si and Cl.

3) Identify the hazards associated with using potassium metal as a reducing agent.

4) Interpret the structure of a silylene complex in the context of VSEPR

5) Describe experimental data (X-ray structures, NMR spectroscopy) used to characterize silylene compounds.

6) Rationalize the authors' use of citations.

Implementation Notes

This LO has not been used yet, but we recommend assigning these problems for the students before class, so that they come prepared to discuss the paper in class. 

Time Required
variable, depends upon implementation. If students read the article and look at the questions before class, the discussion/group work could fit into a 45-60 minute class period.
Evaluation Methods

One possible method of evaluation is to collect student answers to the guiding questions before the discussion takes place in class and/or collect student answers after the class discussion and/or collect answers written by small groups during the discussion.

Evaluation Results

This LO has not been implemented yet.
