Abstract
The chemistry of boron-nitrogen compounds is a field of great interest to the inorganic chemist. Although for a time after Stock and Pohland first synthesized borazine in 1926 (45), developments in the field were slow, within the past twenty years the amount of research in borazine chemistry has increased tremendously. Today, large numbers of borazine derivatives, both symmetrically and unsymmetrically substituted, are known and have been well characterized. The widened use of spectroscopy, particularly infrared, Raman and nuclear magnetic resonance spectroscopy, has helped the characterization of these new borazine derivatives. Although some work has been done in formation of a stable sigma bond between boron and a metal, compounds containing such a bond are comparatively new (30). Most of this work has been done with a variety of arninoboranes and manganese carbonyl. The author thought it would be interesting to see if a compound containing such a boron-manganese sigma bond could be formed using a borazine as a starting material. Guttmann, Meller and Scha~hel (20) have reported the formation of cyclopentadienylborazines containing a sigma bond between the boron of the borazine ring and the carbon of the cyclopentadiene. However, further work was needed on these compounds to characterize them more fully. Brennan, Dahl and Schaeffer reacted B-trichloroborazine with glacial acetic acid to form the (amino)diacetatoborane dimer (5). It was thought by the author that the (methylarnino)diacetatoborane dimer could be formed by a similar reaction between glacial acetic acid and B-trichloro-N-trimethylborazine. Also, it was thought that the (dirnethylamino)diacetatoborane dimer could be formed by reaction of (dirnethylamino)dichloroborane with either glacial acetic acid or silver acetate, thus forming the series [(AcO)2BNH2]2, [AcO)2BNH(CH3)]2 and [AcO)2BN(CH3)2]2. B-trichloroborazine and B-trichloro-N-trirnethylborazine were also reacted with silver acetate to illustrate the replacement of the chlorine on boron by the acetate group.
