Abstract
Abstract The FAB spectra of the adducts trans-Pd(L)2Cl2 (1: L=DIAZEPAM, D=7-chloro-1,3-dihydro-1- methyl-5-phenyl-2H-1,4-benzodiazepin-2-one; 2: L= PRAZEPAM, P=7-chloro-1-(cyclopropylmethyl)-1,3- dihydro-5-phenyl-2H-1,4-benzodiazepin-2-one) and of the cyclometallated derivatives [Pd(L=H)Cl]2 (L=D, 3; L=P, 4), Pd(Ph3P)(L=H)X (L=P, X=Cl, 5; L=D, X=Br, 6), Pd(D)(D=H)Cl (7) have been studied in detail. The main gas-phase fragmentation pathways of 1 and 2 consist in sequential HCl losses, while for compounds 3 and 4 only primary Cl· loss is observed. A peculiar behaviour is observed for 5 and 6, i.e. the lack of protonated molecular ions.
