Blue Tetrakis(diisopropylamino)-cyclo-tetraborane and Yellow Tetrakis(tetramethylpiperidino)tetrabora-tetrahedrane

Blue Tetrakis(diisopropylamino)-cyclo-tetraborane and Yellow Tetrakis(tetramethylpiperidino)tetrabora-tetrahedrane

The colored boranes closo‐1 and cyclo‐2 are obtained upon dehalogenation of sterically hindered diaminodichlorodiborane(4) 3. The TMP groups of 1 cause the formation of a tetrahedrane, whereas in 2 the diisopropylamino substituents stabilize the bent four‐membered ring. TMP=2,2,6,6‐tetramethylpiperi...
