Novel nitrogen-bridged diazocines (triazocines) were synthesized that carry a formyl or an acetyl group at the CH 2 NR-bridge and bromo- iodo-substituents distant phenyl ring. The photophysical properties investigated in acetonitrile water. As compared to previous approaches yields of intramolecular azo cyclizations increased (from ≈40 60%) using oxidative approach starting from corresponding a...

2-Borylated porphyrins reacted with Pt(cod)Cl2 to give b-to-b platinum-bridged porphyrin dimers, which were converted to b-to-b directly linked porphyrin dimers through triphenylphosphine-mediated reductive elimination. Similar reactions of 2,18-diborylated Ni(II)–porphyrin and Zn(II)–porphyrin gave the corresponding doubly b-to-b platinum-bridged porphyrin dimers. Treatment of the doubly b-to-...

Two ethylene-bridged methylaluminium amidinates and one aluminium amidinate containing three terminal trimethylstannyl-ethynyl groups interconnected by π-coordinated potassium ions were prepared in situ. The re-oxidation of the ethylene-bridged compound by iodine followed by further reduction using the same activation procedure demonstrated the versatility of the approach. The reactivity of an ...

Results: Approximately 80% of patients had AWR with component separation and 8% had a bridged repair. The most frequently used mesh was porcine (Strattice, 56.5%), followed by bovine (Surgimend, 31.1%) and human (Alloderm, 10.9%). There were 31 (16.2%) hernia recurrences with a surgical site occurrence rate of 25.1%. Among these patients, 13% had hernia recurrence within 3 years, while 16.7% at...

Size exclusion chromatography and centrifugation separation protocols were developed and compared for isolating enriched fractions of phenylethynyl-bridged metal nanoparticle dimers and trimers from the monomeric particle starting material. Both methods enabled the isolation of enriched fractions of a desired array without causing significant sample aggregation or replacement of the phenylethyn...
