Porphyrins. 32. Mass spectrometric study of <i>vic</i>-dihydroxy- and <i>vic</i>,<i>vic</i>-tetrahydroxychlorins

Abstract

A mass spectrometric investigation has been carried out on dihydroxy- and tetrahydroxychlorins, derivatives of vic-diols of etioporphyrin-1 and octaethylporphyrin, the vic-diol and vic, vic-tetraol of the tetraethyl ester of coproporphyrin-1, dimers of bischlorides linked together with a methylene bridge, and also of their trimethylsilylated products. It was established that in the spectra of porphyrin diols the molecular ion peaks were either of low intensity or were completely absent. In the spectra of trimethylsilyl derivatives, the ion peaks of maximum intensity were caused by the silylation of only one of each two neighboring hydroxyl groups in the initial compounds.
