Abstract
Electron Impact (El) mass spectrometric behavior of [PtCl(η1C3H5] (L2=2PPh3, Ph2P-C2H2PPh2) and {PtCl[CHCH2C(CN)2C(CN)2CH2]( L2)} are described and discussed in detail with the aid of linked scans exact mass measurements and collisional experiments. The cases of [Mn(η1-C3H5)(CO)5] and {Mn[CHCH2C(CN)2C(CN)2CH2](CO )5} are also reported. Results are interpreted in terms of the different stability of η1-allyl complexes as a function of coordinated ligands and of the possibility of η3-allyl bond formation; these data are compared with mass spectrometric features of the corresponding cyclopentyl derivatives. For the latter a retro-synthetic reaction to tetracyanoethylene and the original allyl complex is described. © 1986.Pubblicazioni consigliate
