- Alexey Leontyev was just tagged in a comment: @Alexey Leontyev Also mentioned amberlyst-15! I checked our inventory and we don't have any, but have a bunch of different Amberlites, some of which are acidic. Supposedly Amberlite IR-120 is strongly acid, I see papers on google scholar that mention it as a catalyst for esterification! I might give it a shot as an acid for the Lewis Acid reaction and for other reactions (microwave? Mechanochem?) Amberlite IR400 is basic, and the only amberlyst we have is 21, which is also basic. I might also give silica-sulfuric acid a try (not using the ClSO3H prep, just the sulfuric acid + silica prep)....
- Alexey Leontyev was just tagged in a comment: @Alexey Leontyev though the question was extra credit, no one answered. :( I am currently working with @Omar Villanueva - he has explicitly added portions to our online labs about the SDGs, green chemistry, and systems thinking. Generally the answers have been reasonable, but I need to sift through them at the end of the term and see how they did. Your post gives me an idea for sorting through them to look for biodegradability, solubility etc....
- Alexey Leontyev was just tagged in a comment: Posted this in the forum, but getting no traction. Re-posting here and tagging @Krystal Grieger and @Alexey Leontyev . I am looking for an assessment for my toxicology course - I'd like to have both content and attitudes. Haven't found anything using google, but maybe I'm not looking in the right spots. Have also checked out various toxicology sites & can find questions related to certification but not just a course....
- Alexey Leontyev was just tagged in a comment: Hey @Alexey Leontyev ! I have some experiments etc. which I'm always happy to chat and share. We have a "greener inorganic" group as well I am happy to add you to if interested (just started so not much in there yet). Otherwise there is also a few experiment in one of the curated collections as well (https://gctlc.org/greener-inorganic-labs)! I'd love to hear if there's anything specifically you're interested in, or happy to discuss some of the current experiments being conducted at your institution and some possible alternative substitutions or ways to develop them into greener experiments!...
- Alexey Leontyev was just tagged in a comment: @Alexey Leontyev out of curiosity, how would you recommend wording a question like this in an assessment (e.g., exam)? You said above that, as worded, it's pretty vague...would you give more details to students? Or would you leave it intentionally broad? I kind of like it as is... A good critical thinking question and that way, you can look for the major bullet points Jerald and Dave outlined above, but would love to know your thoughts....
- Alexey Leontyev was just tagged in a comment: Hey @Alexey Leontyev ! 👋 That's a super interesting question. It really seems like the "greenness" depends on the specific reaction.Like, what if you had a chiral starting material? The SN2 reaction would give you a specific stereoisomer, which could be considered "greener" since you're making a desired product with high selectivity. But what if your starting material is really sterically hindered and the SN2 reaction is super slow? You might need a ton of energy or a harsher solvent to get it to go.What do you all think?I'm curious to hear what other factors you guys consider when trying to decide which reaction is "greener."...
