Porphyrin’s Hole Plugged By Ethylene
A porphyrin with a C=C unit in the middle, rather than a conventional metal atom, displays unusual electronic properties, Thomas P. Vaid of the University of Alabama reports (J. Am. Chem. Soc., DOI: 10.1021/ja205738z). Vaid reacted a cobalt porphyrin with diiodoacetylene to yield a porphyrin with a diiodoethylene group attached to two of the nitrogen atoms. Subsequent reduction of the porphyrin . . .
