Reactions of N,N'-Dimethylurea with Some Boron-Nitrogen Compounds
Abstract
Reaction of borazines, (-RBNR-)3, with N,N -dimethylurea, (R HN)2 CO (R = CH3), result in the formation of 1,3,5-triaza-2,6-diboracyclohexane-4-ones (1;R = C2H5 and R = H or CH3) or of 1,3,5-triaza-2-boracyclohexane-4,6-diones (2,R = C6H5 and R = CH3). Bis(dimethylamino)organylboranes, (C H 3) 2N2BR(R = ch3, C2H5, C6H5), undergo a partial transamination with N,N -dimethylurea to yield triply bridged diboron species RBN(CH3)2 NCH3CONCH3 NCH3CONHCH3BR containing four-coordinate boron. The reaction of (dimethylamino) diorganylboranes, (CH3)2NBR (R = C2H5, n-C3H7, C6H5), with N,N -dimethylurea at temperatures near 150 C proceeds by an amino group exchange and the process yields (methylamino)diorganylboranes, (CH3)HNBR2, and N,N,N -trimethylurea. Borazines, Aminoboranes, N-borylated ureas.
