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).

A series of 2-halo-1,3,2-diazaboracycloalkanes has been prepared by (a) the interaction of trialkylamine-trihaloboranes with alphatic α,ω-diamines, (b) displacement of dimethylamino groups of 2-dimethylamino-1,3,2-diazaboracycloalkanes with halogen through interaction with boron trihalides, and (c) a transhalogenation reaction. The 2-halo-1,3,2-diazaboracycloalkanes are thermally rather stable but are very reactive toward moisture and oxygen. The boron-bonded halogen is readily replaced by organic groups through interaction with Grignard reagents. All compounds have a characteristic BN absorption in the 1510-1540-cm-1 region of their infrared spectra and the proton magnetic resonance spectra are consistent with their structure. In the mass spectra, the parent peaks P+ are generally less abundant than the (P - 1)+ peaks.
