Initiated by CCl3Br, phenols undergo efficient ortho-selective oxidative cross dehydrogenative coupling (CDC) with trimethylamine. When tetramethylethylenediamine (TMEDA) is used instead of trimethylamine, oxidative carbonâcarbon activation coupling (CAC) could occur to give the same salicylamines together with CDC by-products. These reactions are accelerated by a gold salt.

Phenols were converted to their magnesium salts with the MgCl2-Et3N base system and subsequently reacted with Eschenmoser's salt, affording N,N-dimethyl substituted benzylamines in high to excellent yields. A series of mono N-substituted benzylamines were prepared in one-pot syntheses by ortho-formylation of phenols to corresponding salicylaldehydes, which in turn reacted with amines to imines. The imines were subsequently reduced to mono N-substituted benzylamines. Some of these benzylamines were further converted, without work-up, to mono N-substituted dihydro-2H-1,3-benzoxazines.
