Reaction of 1,2,3-Selenadiazoles with Phosphines

Reaction of 1,2,3-selenadiazoles with boranes

“…There is particular interest in an investigation of the molecular structure of 1,2,3-selenadiazoles because few structures have been confirmed by X-ray analysis according to literature data [9][10][11][12].…”

“…According to the X-ray analysis of other selenadiazoles [9][10][11][12][13] the CSe bond is also shorter than the N-Se. The N(2)-N(3) and C(4)-C(5) bonds are lengthened when compared with standard values for N=N and C=C bonds [14] and this confirms the aromatic character of the selenadiazole ring.…”
