Carbonyl complexes of transition metalswith stabilized germylenes
The germylenes based on substituteddiethylenetriamine and dialcohols wereused as ligands for synthesis of new mono-and disubstituted (cis-/trans-) germaniu-m(II) molybdenum and tungsten carbonylcomplexes. The germylenes based on dia-lkanolamines and pyridine-containing dia-lcohols (O-ligands) gives cis-digermaniumcomplexes. On contrary, germylenes basedon diethylenetriamines (N-ligands) givetrans-digermanium complexes.

Efficient synthesis of N-substituted pyrrolescatalyzed by a novel an organiceinorganichybrid solid acid catalyst
The inorganiceinorganic hybrid complex[MIMBS]3PW12O40 was used as an efficientcatalyst for the preparation of N-substitutedpyrroles. The heterogeneous catalyst can beeasily recycled and reused without loss of itsactivity for several times. [MIMBS]3PW12O40as catalyst leads to short reaction time, highyields of the products.
Synthesis and characterization of silver andgold NHC complexes: Crystal structures andmass spectral studies
Gas phase chemistry and crystal structuresof silver and gold complexes with N-hetro-cyclic carbenes were investigated. We gen-erated a species [Au(SBzlCy)(PhChC)] whichis an intermediate of carboxylation and hy-dration of terminal alkynes by the coordi-nation of phenyl acetylene to the charge-tagcontaining gold complex in gas phase.

Ferrocenyl (P,N)-diphosphines incorporatingpyrrolyl, imidazolyl or benzazaphospholylmoieties: Synthesis, coordination to group10 metals and performances in palladium-catalyzed arylation reactions
Ferrocenyl diphosphines incorporating phos-phorus atoms substituted with nitrogen-containing heterocycles of pyrrole, imidazoleandbenzazaphosphole typewere synthesizedand characterized. Their coordination to pal-ladium and platinum group 10 transitionmetals was exemplified, and the perfor-mances obtained in palladium-catalyzed ter-minal alkynes arylation and Suzuki cross-coupling reactions using bromoarenes andchloroarenes are reported.

Synthesis and characterization of acet-amidine rhodium(III) cationic methyl com-plex, trans-[Rh(Acac)(PPh3)2(CH3){NH]C(NH2)CH3}][BPh4], produced by ammina-tion of acetonitrile ligand in trans-[Rh(A-cac)(PPh3)2(CH3)(CH3CN)][BPh4]
The rhodium(III) cationic methyl acet-amidine complex, trans-[Rh(A-cac)(PPh3)2(CH3){NH]C(NH2)CH3}][BPh4],is formed by ammination of coordinatedacetonitrile in trans-[Rh(A-cac)(PPh3)2(CH3)(CH3CN)][BPh4]. Z-config-uration of the acetamidine ligand isstabilized by hydrogen bonding with theoxygen atom of the acetylacetonate ligand.
Tetrahedral silicon-based luminescent mol-ecules: Synthesis and comparison of ther-mal and photophysical properties by variouseffect factors
Tetrahedral silicon-based luminescent mol-ecules with N-heterocycle functional groupswere synthesized and can be potentiallyused as blue emitters, host materials orhole/electron blocking materials for OLEDs.Various effect factors on thermal and pho-tophysical properties were investigated.These results may give valuable suggestionsto select efficient luminescent materials forOLEDs.

Synthesis, characterisation and aggregationproperties of novel metal-free and metal-lophthalocyanines containing four 21-membered oxatetrathiadiaza macrocycles
A simple strategy for the synthesis of metal-free and metallophthalocyanines containingfour 21-membered oxatetrathiadiaza mac-rocycles is described. The aggregation be-haviours of these phthalocyanines wereinvestigated at different concentrations indimethylformamide. Solvent and concen-tration effects on the aggregation propertiesof the phthalocyanines were determined.

Reactions of (CMe2)(SnMe2) doubly bridgedbiscyclopentadienes with transition metalcarbonyls: Double ring-to-metal migrationof SnMe2
In the reactions of doubly bridged biscyclo-pentadienes (C5H3R(CMe2))(C5H3R(SnMe2))with M(CO)n (M ¼ Fe, Mo), the bridgingSnMe2 group migrates from ligand to thecorresponding transition metals to givecompounds containing the MeSneM units.A plausible mechanism for ring-to-metalmigration is proposed. The photochemistryof complexes containing the MeSneM unitwas also studied.
