✦ Synopsis

Tandem mass spectrometric t e c h n i were used for the characterization of gas-phase titanocenium ions. Decomposition of metastable and collisionally activated C,,H,,Ti+' ions involved cyclopentadienyl-metal b o d rupture, acetylene loss a d dehydrogenation as the prominent processes. The i n t e r d a t e formation of titanium (di)hydride complexes was proposed to explain the selective H, molecule loss. The neutralization-reionization mass spectrum showed a very abundant recovery signal, indicating a high stability for the neutral gas-phase C,,H,,Ti species.

## Abstract Porphyrin derivatives having a galactose or a bis(isopropylidene)galactose structural unit, linked by ester or ether bonds, were characterized by electrospray tandem mass spectrometry (ES‐MS/MS). The electrospray mass spectra of these glycoporphyrins show the corresponding [M + H]^+^ io
