Abstract: | |||||||
Schiff base condensation of Polyaromatic Hydrocarbon (PAH) functionalised aldehydes and a range of alkyl functionalised primary amines was successfully undertaken. Subsequent reduction yielded new PAH-substituted amines and the Mannich-based condensation chemistry of these new amines was explored using HOCH2PR2 precursors to yield (9-anth)CH2N(R)CH2X (X = PAd or PR'2) ligands. The co-ordination of these new monophosphines to a readily available dichloroplatinum(II) metal centre was explored to form cis complexes cis-PtCl2{9- (anth)CH2N(iPr)CH2PAd}2 (2.1d), cis-PtCl2{9-(anth)CH2N(Bz)CH2PAd}2 (2.2d), cis-PtCl2{9-(anth)CH2N(nPr)CH2PAd}2 (2.3d), cis-PtCl2{9- (anth)CH2N(iPr)CH2PPh2} (2.1g) and cis-PtCl2{9-(anth)CH2N(iPr)CH2P(C6H4 o-OCH3)2} (2.1h). Further studies involving synthesis of the chelating bisphosphines [(2-anth)CH2N(CH2PR2)2 and (1-pyr)CH2N(CH2PR2)2] were undertaken. This was achieved using Mannich-based condensation of PAH-functionalised primary amines with HOCH2P(C6H4-o-OCH3)2 and gave rise to interesting behaviour upon co-ordination to a Pt(II) metal centre, with significant broadening observed in both the 1H and 31P{1H} NMR (ω1/2 ca. 73 Hz) spectra of these compounds.
