THE REMARKABLE stability of cyclopentadienylthallium, C,H,Tl, has aroused interest since the first reports of its synthesis from aqueous s o l u t i ~n . ~~~ It forms air-stable, pale yellow crystals, in contrast to the methyl-substituted compound, which is oxidised vigorously by air.4 This stabilit
## Abstract The mass spectrum of msβtetraphenylchlorin was observed to contain a significant porphyrin peak. Attempts to obtain metallochlorin spectra yeilded mainly metalloporphyrin spectra. Sublimation experiments established that the chlorin to porphyrin conversion resulted from electronβimpact
