Creating new substances, sometimes just for the sake of the creation act itself, is an undeniable part of chemists’ nature. Having flawless analytical data of a newly prepared sample always fills one with mystical joy and feeling of omnipotence. And some chemical creatures are so bizarre that the very fact of their isolation and characterization causes reverence of fellow chemists. So welcome to the chemical Panoptikum, a collection of all sorts of weird structures from the recent literature. Don’t be surprised to meet boron very often here, it’s a really weird element.
Triple-charged radical, based on five-electron four-centered bond… Anything is possible in the boron world.
Turns out, if you substitute three out of four pyrrole rings in porphyrin, the macrocycle becomes antiaromatic.
