Magnesiation ortho to boron: Borylbenzenes with an N-methyl-1,3- ethylenediamino group on the boron atom undergo ortho-magnesiation upon exposure to 2,2,6,6-tetramethylpiperidide (TMP)2Mg, and the resulting ortho-magnesiated borylbenzenes can be trapped with electrophiles (see scheme).

Boron- and nitrogen-substituted 1,3,2-diazaboracycloalkanes have been prepared by a transamination between bis(dimethylamino)boranes and α,ω-diamines. Partial substitution of the nitrogen of the diamine does not appear to inhibit this reaction; five-, six-, and seven-membered heterocyclic systems are readily obtained by the described procedure. However, the low yields of product obtained in those reactions involving an olefinic α,ω-diamine indicate that steric factors may play an important role. The mechanism of the formation of the boron-nitrogen-carbon heterocycles is discussed, and some spectroscopic data are briefly evaluated.
