The 1 : 2 adduct of 1-bromo-ortho-carborane and pyridine has been identified as a significant intermediate in the deboronation of ortho-carborane to a nido-anion.

In this work, we present a comparative case study of "ortho-" and "meta-nitrated" catecholic inhibitors of catechol-O-methyltransferase (COMT), with regard to their interaction with the catalytic site of the enzyme and the in vitro regioselective formation of their mono-O-methyl ether metabolites. In particular, the effects of altering the attachment position of the inhibitors' side-chain subst...

Planar chiral h6-arene chromium(0) complexes are finding increasing application in the synthesis of enantioenriched compounds by serving as enantiopure starting materials or ligands for catalytic asymmetric processes.[1,2] Whereas early methods of generating enantiopure 1,2-disubstituted h6-arene chromium(0) complexes relied on resolution of racemates,[3] many methods have been developed recent...

Treatment of [PtI2(COD)] (COD = 1,5-cyclooctadiene) with 2-LiC6H4P(S)Ph2 gives the complex cis-[Pt{κ(2)-2-C6H4P(S)Ph2}2] () containing a pair of ortho-metallated triphenylphosphine sulfide rings. The selenium counterpart, [Pt{κ(2)-2-C6H4P(Se)Ph2}2] (), which exists as cis- and trans-isomers in solution, and the palladium analogues, cis-[Pd{κ(2)-2-C6H4P(X)Ph2}2] [X = S (), Se ()], are obtained b...

Orthokeratology practice in children in a university clinic in Hong Kong Clin Exp Optom, 2008. 91(5): p. 453-60. PURPOSES: The aim of this study was to analyse clinical data of children undergoing orthokeratology (ortho-k) and to investigate patients'/parents' perspective on ortho-k via telephone interviews. METHODS: Clinical records of children undergoing ortho-k from a university optometry cl...

Catalysis with phosphorus P(III) compo­unds (phosphorus trichloride and phospho­rous acid) in the acylation of aniline 3=hydroxy=2=naphthoic acid various media (toluene, octane, chlorobenzene, para=­xylene, ortho=xylene, ortho=chlorotoluene, mesitylene, pseudocumene, n.=deсan, ortho= di­chlo­ro­benzene, mixtures ortho=xylene nitrobenzene) upon boiling vigorous distillation water leads to format...
