Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

Investigation of major metabolic pathways of SFZ-47 in animals The metabolites of SFZ-47 in rabbit urine following oral administration were separated and detected with HPLC and LC-MS methods. On the basis of the chromatographic behavior and mass spectra of the metabolites as well as biotransformation pathways of drugs with the partial structure of SFZ-47, the hydroxylic derivative 4-(3H-1, 2- dihydro-1-pyrrolizinone-2-methylamino benzyl alcohol and the carboxylic derivative 4-(3H-1, 2-dihydro-1-pyrrolizinone-2-methylamino benzoic acid of SFZ-47 were proposed as two potential metabolites and were synthesized.
