Synthesis and characterization of new air stable primary amido substituted diborane(4) derivatives
摘要:
Three new diborane(4) derivatives, 1,2-bis(2,4,6-trimethylanilide)-1,2-bis(dimethyamido)diborane(4) (1), 1,2-bis(2,4,6-trimethylanilide)-1,2-bis(duryl)diborane(4) (2) and 1,2-bis(anilide)-1,2-bis(duryl)diborane(4) (3), have been synthesized and characterized by means of elemental analysis, IR, H-1, DC and B-11 NMR spectroscopy. Additionally, the structures of compounds 1 and 2 have been determined by the single crystal X-ray diffraction technique. The compounds 1 and 2 crystallize in the monoclinic P21/c space group. All of the compounds were found to be air stable. (C) 2010 Elsevier Ltd. All rights reserved.

A neutral 1,4-diaza-2,3,5,6-tetraborinine derivative (3) featuring a 6π ring system has been synthesized and structurally characterized. The prospective aromatic nature of 3 was assessed by single-crystal X-ray analysis, NMR, and UV/Vis absorption spectroscopy as well as computational studies. Furthermore, preliminary reactivity investigations showed that 3 does not only react with diphenyl acetylene
