Cyclocondensation reaction of RNHCH:CHNHSiMe3 with MeBBr2 in the presence of BuLi in pentane/hexane gave dihydro-1,3,2-diazaboroles I (R = Me, Et, CHMe2, CMe3). Reaction of I with KOCMe3 in THF gave 60-70% title compds. II. The crystal structure of II contg. (Me3CO)- and (Me2SiO2)- anions was detd.
