Initiated by CCl3Br, phenols undergo efficient ortho-selective oxidative cross dehydrogenative coupling (CDC) with trimethylamine. When tetramethylethylenediamine (TMEDA) is used instead of trimethylamine, oxidative carbon-carbon activation coupling (CAC) could occur to give the same salicylamines together with CDC by-products. These reactions are accelerated by a gold salt.
Ligands for the Alkali Metals. Part 7. Synthesis and Characterisation of Crown Ether Macrocycles Containing the Di-1-naphthylmethyl Unit as a Novel Steric Barrier

The first examples of crown ethers in which each end of the ether strand is fixed to one blade of a molecular propeller (a dinaphthylmethane) have been synthesised.The resultant steric barriers have been found to slow crown-flexing sufficiently for kinetic processes to be observed with 1H or 13C n.m.r. in the temperature range 200-270 K. vic-Coupling constants for the ethylene oxide segments at ambient temperature indicate a very low proportion of trans-conformer in the conformational mix.The crowns also complex with the alkali cations in solution.
