more exploits with vacuums

learned not to pull a full vacuum on any closed container today, after making a bit of a mess with a round bottom flask filled with drying agent and capped with a septum…i’ve learned now how to deal with bringing it into the glovebox.

still haven’t gotten the hang of the schlenk line, though. need to ask about it. seems like trial and error at the moment, plugging things up and turning things until the desired output happens.

mostly, though, spent the day drying out the disaster of a product from yesterday’s experiment. i’ve yet to do an nmr of it (that’s for tomorrow), so i’ve no idea whether it’s good or not (i’m leaning towards not, as it’s brown, and it’s supposed to be a light tan color). tomorrow’ll probably be spent remaking the precursor to the disaster, and bringing forward the second compound (hopefully both will be okay to react over the weekend, as they’re supposed to be overnight reactions…).
