The title 22-crown-6 unit, C(26)H(28)O(6), comprising of three benzo groups and triethyl-ene glycol, was prepared by the reaction of α,α'-dibromo-p-xylene with 1,8-bis-(2-hydroxy-phen-oxy)-3,6-dioxaoctane in the presence of Cs(2)CO(3) with tetra-hydro-furan (THF) and recrystallized from dichloro-methane-hexane (1:20 v/v) at room temperature.

A bis-chelating ligand (L1), made of two 7-(p-anisyl)-1,10-phenanthroline (phen) subunits connected with a p-(CH(2))(2)C(6)H(4)(CH(2))(2) spacer through their 4 positions, has been prepared, using Skraup syntheses and reaction of the anion of 4-methyl-7-anisyl-1,10-phenanthroline with alpha,alpha'-dibromo-p-xylene. Its Fe(II) complex, [FeL1(dmbp)](PF(6))(2), was prepared

The third-generation bis(1-pyrazolyl)methane ligands p-C(6)H(4)[CH(2)OCH(2)CH(pz)(2)](2) (L(p), pz = pyrazolyl ring) and m-C(6)H(4)[CH(2)OCH(2)CH(pz)(2)](2) (L(m)) have been synthesized by the reaction of (pz)(2)CHCH(2)OH with NaH followed by alpha,alpha'-dibromo-p-xylene or alpha,alpha'-dibromo-m-xylene. The reaction of L(p) with AgBF(4), AgPF(6), and AgO(3)SCF(3) yields the new

The stereoisomers of alpha,alpha'-bis[3-(N,N-diethylcarbamoyl)-piperidino]-p-xylene (1) were synthesized. Rac ethyl nipecotate was resolved by diastereomeric (-)-D- and (+)-L-tartrate salt formation. The enantiomeric esters were hydrolyzed to the corresponding nipecotic acids, which were then converted into t-BOC derivatives. Treatment of the latter
