Thienyl pyridine platinum

The spectroscopic properties of platinum complexes containing bidentate C-deprotonated 2-phenylpyridine or 2-(2 -thienyl)pyridine ligands was previously studied by von Zelewsky [14] and others [15]. These complexes typical-... 

A series of iridium(III) complexes of the type Ir(L-L)3 have been prepared by reaction of a glycerol solution of Ir(acac)3 and L-L (2-arylpyridine or 2-aryl-l-qui-noline) in an open vessel equipped with a reflux condenser. 5 This represented an improvement on the analogous methodology using a domestic microwave oven as less ligand was required, but YIFs were only 0.82-1.2. In the case of 2-phenyl-l-quin-oline, a 10% yield of the Ir complex was obtained in 20 min, while only trace amounts were produced after 10 h of conventional reflux. Cyclometallated platinum(II) complexes of the type PtCl(L-L)L where L-L = 2-phenylpyridine, 2-(2 -thienyl)pyridine, or benzoquinoline have also been prepared but not with any enhancement in yield (YIF = 0.58-1.0). 55...
