Nitrogen adduction by three coordinate group 10 organometallic cations: Platinum is favoured over nickel and palladium

Abstract

Previous studies have shown that highly reactive product ions formed by collision-induced dissociation (CID) of precursor ions generated via electrospray can readily react with residual solvent or drying gases, especially in ion trap mass spectrometers. Here we report on the rapid addition of nitrogen to the coordinatively unsaturated organoplatinum cation, [(phen)Pt(CH3)]+ (phen = 1,10-phenanthroline) formed via decarboxylation of the acetate complex [(phen)Pt(O2CCH 3)]+. This contrasts with the related coordinatively unsaturated group 10 cations: addition of nitrogen to [(phen)Pd(CH 3)]+ occurs at longer reaction times, whereas addition of nitrogen to [(phen)Ni(CH3)]+ is virtually non-exis..
