The heater block glowed a dull red color, observable with room lights turned off. The ballast tank was filled to 300 torr with oxygen, and fluorine was added until the total pressure was 901 torr. . . And yes, what happens next is just what you think happens: you run a mixture of oxygen and fluorine through a 700-degree-heating block. "Oh, no you don't," is the common reaction of most chemists to that proposal, ". . .not unless I'm at least a mile away, two miles if I'm downwind. " This, folks, is the bracingly direct route to preparing dioxygen difluoride, often referred to in the literature by its evocative formula of FOOF. Well, "often" is sort of a relative term. And a hard core it is!
FOOF is only stable at low temperatures; you'll never get close to RT with the stuff without it tearing itself to pieces. Even Streng had to give up on some of the planned experiments, though (bonus dormitat Strengus?). In the Pipeline: Cadmium is bad news. Lead and mercury get all the press, but cadmium is just as foul, even if far fewer people encounter it. Never in my career have I had any occasion to use any, and I like it that way. There was an organocadmium reaction in my textbook when I took sophomore organic chemistry, but it was already becoming obsolete, and good riddance, because this one of those metals that's best avoided for life.
It has acute toxic effects, chronic toxic effects, and if there are any effects in between those it probably has them, too. Fortunately, cadmium is not well absorbed from the gut, and even more fortunately, no one eats it. Dimethyl cadmium, then, represents the demon plunked in the middle of the lowest circle as far as this element is concerned. Even though dimethylcadmium does not instantly turn into a wall of flame, it can still liven the place up. I'm saddened to report that the chemical literature contains descriptions of dimethylcadmium's smell. April 5, 2013 Posted by Derek. Explain xkcd.
