    The thioacetone doesn’t have an -SH pair . The Sulfur has a double bond with the central carbon.
    The ‘acetone’ tells you it is like a ketone, and they have C=O bonds, so considering sulfur is also group 6, you can see why I thought you might be incorrect about it.

    After some looking around it seems that AA was created before Klapötke studied it in 2010. A 2012 series of experiments by another German team seems to indicate it was previously mistaken for Isocyanogen Tetraazide, another twitchy form of C2N14, which quickly coils up to become AA before it can be properly investigated. Their article was published in 2013 (before this video) and claims to include the first measurements of actual Isocyanogen Tetraazide. DOI: 10.1002/anie.201209170

    That phrase should horrify anyone.
    We can accurately measure the distances between stars.
    We can accurately measure the distance between the nucleus of an atom and its orbitiing electrons.
    We can accurately measure the time between two wingbeats of a hummingbird.
    But we can't tell when this thing we made is going to go "kaboom" and take anything and everything in close proximity into glorious nonexistence with it.

      Alexis Harper Glacial acetic acid? Damn, you haven't seen nothing yet.
      I've had one unfortunate encounter with a most hideous smell. I'm not easily startled by a smell, I'll take amines bt the dozen and thiols if I must, but this one was different. It was the half-annual lab cleaning day and I had inherited a round bottom flask carefully sealed by its original owner who had probably forgotton all about it. The only indication I had of what I was to experience was a small drawing on the side in permanent marker. It showed a benzene ring with methyls in the 2- and 6-positions and at the first position it showed an awkward characteristic group: "NC". Knowing of the legends foretold about this class of compound, of its unimaginable stench and indiscribable smell, our olfactory system having seemingly evolved specific receptors that serve no purpose but to make an entire class of purely synthetic compounds with no known representation in nature entirely unbarable to human noses, I was understandably cautious, hesitant even to open up the flask. I had cleaned out my fumehood entirely except for that one flask so it had to happen. I collected all my courage, carefully undid the parafilm wrapping around the stop and then slowly twisted the stop and took it off to release the most aweful stench I have ever smelled. I immediately put the fumehood window down to increase the airflow and get rid of the stench but it managed to diffuse against the flow of air in large enough quantities that it remained unbarable. I decided to return the stop to the flask and wait for the stench to subside. When it had, I returned with a washbottle of acetone which I used to spray into the flask quickly before stoppering again. After all I had endeavoured to clean this flask and clean it I would. Once dissolved, the stench lost some of its potency, and once introduced to the waste container, it was at least further masked, but the same stench unmistakenly remained for several days. Looking back now, it likely reacted with acetone, acids and thhe occasional amine in the waste in Pazzerini and Ugi reactions, neutralizing the smell. Still, I will never do anything with isocyanides anymore.
