Synthesis and study of 1,3-di-tert-butyl-2,4-dimethyl-1,3-diaza-2,4-diborolidine.
Cyclocondensation of MeB(NHCMe3)2 with Me2Sn(CH2Br)Br in presence of BuLi-Et2O gave 60% stannaborolidine I. Reaction of I with MeBBr2 in pentane gave an adduct, which on refluxing in THF, gave 15% title compd. II. The structure of I was detd. by x-ray crystallog.
