Luminescent phosphinocrown-containing gold(I) complexes: Their syntheses, spectroscopic studies and host–guest chemistry
摘要:
A series of phosphinocrown ether-containing gold(I) complexes, [Au(Ph2P-b15c5)Cl] (1), [Au-2(mu-i-mnt)(Ph2P-b15c5)(2)] (2) and [Au-2(mu-dtc)(Ph2P-b15c5)(2)](PF6) (3) (b15c5 = benzo-15-crown-5, i-mnt(2-) = 1,1-dicyanoethylene-2,2-dithiolate, dtc(-) = diethyldithiocarbamate) have been synthesized. Complexes 2 and 3 center dot NaPF6 have also been structurally characterized. The emission bands at ca. 500-515 nm for 2 and 3 upon photo-excitation are tentatively assigned as derived from excited states of S -> Au ligand-to-metal charge transfer (LMCT) origin. These complexes have been shown to serve as host for the specific binding of various metal cations. (c) 2005 Elsevier B.V.. All rights reserved.
Transition Metal Phosphine Complexes Possessing a Phase Transfer Function. Preparation and Catalytic Reactivity of Palladium Phosphine Complexes Containing Crown Ethers
Crown-functionalized triarylphosphines and their palladium complexes were synthesized and characterized. The palladium complexes were found to fulfil the concerted function of the transitionmetal catalyst and the phase transfer catalyst in the two-phase reduction of 1-chloromethylnaphthalene with formate salts.

A ditopic receptor based on gold(I) phosphine thiolate complex [(B15C5Ph2P)Au(SC6H4NHCONHC6H5)] (1) together with a related crown-free analogue, [(Ph3P)Au(SC6H4NHCONHC6H5)] (2), have been designed and synthesized and their photophysical properties studied. Complex 1 featured both a benzo-15-crown-5 cation-binding unit in the auxiliary phosphine ligand and a urea-functionalized thiolate as an anion
