Highly substituted alkenylsilanols (1), readily prepared from commercially available simple starting materials, are efficiently coupled with aryl or alkenyl halides in the presence of tetrabutylammonium fluoride (TBAF) and a palladium(0) catalyst. Yields are generally high and the reactions are highly stereoselective and compatible with a wide range of functional groups.

The scope of the Suzuki-cross-coupling reaction of 6-haloimidazo[1,2-a]pyridines is dependent on the availability of the (hetero)arylboronic acids. Thus, with the aim to develop expanded applications of (hetero)arylations of imidazo[1,2-a]pyridines, we investigated the Negishi- and Stille-cross-coupling reactions at the 6-position. Remarkably, attempts to aply the Negishi-cross-coupling conditions to the organozinc derivative prepared from 6-haloimidazo[1,2-a]pyridine via a lithium-zinc exchange led to the 5-phenyl compound 3 in 54 percent yield instead of the desired 6-phenyl-isomer (Scheme 1). In contrast, various commercially available halogenated five- or six-membered-ring heterocycles were efficiently coupled to the 6-(trialkylstannyl)imidazo[1,2-a]pyridine under Stille conditions (Table 2).

Dibenzazepinyl dichlorophosphine 2 reacts with (R,R)-2,3-O-isopropylidene-threitol (3) in Et2O solution to afford gram-quantities of the enantiopure macrocylic phosphoramidite (all-R)-6, which may be seen as a formal dimer of classic phosphoramidite P-alkene hybrid ligands. Complexation experiments with PdCl2 reveal highly selective formation of the trans-dinuclear complex (all-R)-11. The corresponding bulkier and rigidly trans-eclipsed 1,4-diol (S,S)-bis-hydroximethyl-9,10-dihydro-9,10-ethaneanthracene (4) does not favor macrocycle formation and exclusively leads to the new dibenzazepinyl phsophormaidite P-alkene ligand 7, which in Pd-catalyzed asymmetric allylic amination comes the well-known ?privileged? binol-derived P-alkene analogue 1 close in terms of enantioselection.

Six complexes consisting of either 2,6-bis(1H-benzimidazol-2-yl)pyridine (bbp) or 2,2?:6?,2?-terpyridine (tpy) moieties coordinated to ruthenium(II) and attached to (pentaphenoxy)cyclotriphosphazene were synthesised and structurally characterised by single-crystal X-ray diffraction techniques. Two of the complexes are the first examples of structurally characterised mono-protonated Ru(bbp)(tpy) complexes. The new complexes were studied by NMR, electronic absorption and vibration spectroscopy to gain an understanding of their physical characteristics. Remarkably the mono-deprotonated form of the bbp ligand, but only when attached to (pentaphenoxy)cyclotriphosphazene by a pyridyl phosphoester linker, shows an equivalence of the benzimidazole/benzimidazolate moieties on the NMR time scale, but not on the electronic time scale, as evidenced by UV-Vis and resonance Raman spectroscopy.

Polystyrenes have been synthesized with terminal groups of luminescence square-planar platinum(II) complexes, which can be conceptually regarded as plane-coil diblock copolymers. They can self-assemble into spherical micelles with a core of polystyrenes and a corona of planar platinum(II) complexes in the chloroform/methanol mixture solvents, while free-standing bilayered sheets form in the toluene/methanol mixture solvents. With increasing methanol content in the latter case, where the solvent quality was highly deteriorated for polystyrene blocks, the sheetlike nanostructures are readily transformed into spherical micelles. Pt···Pt and/or pi-pi stacking interactions between the planar platinum(II) blocks contributed significantly to these aggregate morphologies and their evolutions, leading to remarkable luminescence enhancements. This work represents a novel approach to design and synthesize luminescence platinum(II) plane-coil diblock copolymers, in which the planar platinum(II) complexes are for the first time regarded as an individual block for the creation of block copolymers and micellelike aggregates in solution.

Thioesters were synthesized via palladium-catalyzed carbonylation of thioacetates and aryl iodides. S-Aryl thioacetates coupled with carbon monoxide and aryl iodides to afford the desired S-aryl thioesters in good yields. The reaction showed good functional group tolerance toward fluoro, chloro, ketone, ester, aldehyde, cyano, and nitro groups. The tandem reaction of the direct S-arylation of aryl iodides from potassium thioacetate (KSAc) and subsequent carbonylation of the intermediates S-aryl thioacetates provided S-aryl thioesters in moderate-to-good yields.
