A designed receptor for pH-switchable ion binding in water
Tajc, Stephen G.,Miller, Benjamin L.
, p. 2532 - 2533 (2006)
Molecules with conditional (switchable) properties are of considerable fundamental interest and are potentially useful for a broad range of applications, including chemical sensing. We have prepared a novel receptor, derived from the peracylation of cyclo
Synthesis of facial cyclometalated iridium(iii) complexes triggered by tripodal ligands

experimental part, p. 9519 - 9525 (2012/09/11)
The tripodal ligands composed of the 1,3,5-trisubstituted cyclohexyl moiety as a molecular scaffold and 2-phenylpyridyl moieties as a coordination site were designed. The homoleptic cyclometalated fac-Ir(C^N)3 complexes could be obtained by the reaction of IrCl3·nH2O with the designed tripodal ligands. The single crystal X-ray structure determination confirmed the fac configuration and a distorted octahedral geometry with three intramolecular cyclometalated 2-phenylpyridyl ligands surrounding the iridium metal center. Also, the cyclohexyl scaffold was found to serve as a flexible scaffold to induce the fac configuration. The thus-obtained homoleptic cyclometalated fac-Ir(C^N)3 complexes exhibited a broad emission band in the emission spectra at 298 K.

Page/Page column 17-18, (2008/06/13)
The present invention relates to iodine containing compounds containing a central optionally substituted cyclohexane central moiety allowing for the arrangement of three iodinated phenyl groups bound thereto. The invention also relates to the use of such diagnostic compositions as contrast agents in diagnostic imaging and in particular in X-ray imaging and to contrast media containing such compounds.
The polyhomologation of 1-boraadamantane: Mapping the migration pathways of a propagating macrotricyclic trialkylborane
Wagner, Carl E.,Kim, Jang-Seob,Shea, Kenneth J.
, p. 12179 - 12195 (2007/10/03)
Trialkyl and triaryl organoboranes undergo multiple, repetitive homologations upon reaction with dimethylsulfoxonium methylide (1). This multiple homologation reaction, or polyhomologation, produces polymethylene in a living reaction. Applying the polyhom

, (2008/06/13)
The present invention provides branched polyalkylene glycols useful as a chemically modifying agent for physiologically active polypeptides, wherein two single-chain polyalkylene glycols are linked to a group having a cyclic structure other than a plane structure, and wherein a group having reactivity with an amino acid side chain, an N-terminal amino group or a C-terminal carboxyl group in a polypeptide or a group convertible into the group having reactivity is linked to the group having a structure other than a plane structure.
1-Boraadamantane blows its top, sometimes. The mono-and polyhomologation of 1-boraadamantane
Wagner, Carl E.,Shea, Kenneth J.
, p. 3063 - 3066 (2007/10/03)
(equation presented) 1-Boraadamantane·THF (3) reacts with 1 equiv of dimethylsulfoxonium methylide (4) to afford a monohomologated product. The polyhomologation of 1-boraadamantane·THF by ylide 4 followed by oxidative cleavage generates star polymethylene
