## Abstract Adducts of the quaternary protoberberine alkaloids (QPA) berberine, palmatine, and coptisine were prepared with nucleophiles derived from pyrrole, pyrazole, imidazole, and 1,2,4‐triazole. The products, 8‐substituted 7,8‐dihydroprotoberberines, were identified by mass spectrometry and 1D
The mass spectra of several compounds with bonds between transition metals and main group IV elements are discussed. Ionization potentials (1) and appearance potentials of [M'X31+ ions (A) were measured and bond dissociation energies D(M-M') calculated. Values of D(Mo-Sn) from (1)-CgHJ2Mo-(L)SnMe, w
## Abstract Two novel strategies for coordinating TTF to transition metal centers have been developed. The reaction of tetrathiafulvalene (TTF) or 3,4‐dimethyltetrathiafulvalene (__o__‐Me~2~TTF) with [Pt(η^2^‐C~2~H~4~)(PPh~3~)~2~] leads to the π complexes [Pt(η^2^‐TTF)(PPh~3~)~2~] (1) and [Pt(η^2^‐
