A direct synthesis of 2,9-dimethyl-1,10-phenanthroline has been developed. The method involves a Skraup type of reaction between o-phenylenediamine, crotonaldehyde, and either arsenic(V) oxide or sodium m-nitrobenzenesulphonate. Some derivatives of 2,9-dimethyl-1,10-phenanthroline have been characterized.

The direct synthesis of sterically hindered, partially etherified derivatives of tetrakis(2-hydroxyphenyl)ethene is reported by using the McMurry reductive olefination reaction on a range of differentially substituted 2,2′-dialkoxy benzophenone substrates. Three orthogonal protection strategies are demonstrated, incorporating β-silylethyl, 3-butenyl, and tert-butyl protecting groups, respectively, into the starting benzophenones. The latter proved most efficient, with both the McMurry coupling and deprotection steps occurring concomitantly under the McMurry conditions to directly yield the desired bis(2-hydroxyphenyl)-bis(2-methoxyphenyl)ethene as a 1:1 mixture of E- and Z-diastereoisomers.Key words: preorganized polyaryloxide ligands, McMurry olefination, titanium trichloride, supramolecular chemistry, tetrakis(2-hydroxyphenyl)ethene, 2,2′-disubstituted benzophenone.

Various triethylphosphine coordinated gold(1) mercaptides of formula Et3PAuSR (R = Me, Et, Pr, Bu, Bu1, Ph, CH2Ph, β-C10H7, and CH2CH(NH2)C02H), and related sulphur derivatives of formula Et3PAuY (Y = SCN, SC(S)Net2, SC(S)OEt, and SC(NH2)NH2+Br-) have been prepared. Under appropriate conditions, displacement of the sulphur group from the gold atom is observed, either by another sulphur nucleophile, e.g. Et3PAuSR + Et2NCSS- → Et3PAuSC(S)Net2 + RS-, or by a. nucleophile such as Cl-, Br-, I-, NO3-, or CN-.
