As. Balueva et al., SYNTHESIS AND SOME PROPERTIES OF PLANAR 4-DIPHENYLPHOSPHINO 1,3,2-DIOXABORINANES, Russian chemical bulletin, 43(9), 1994, pp. 1561-1567
Fused 1,3,2-dioxaborinanes, derivatives of 4-diphenylphosphino- and ph
enylphosphoryl-4H-1,3-dioxa-2-boraphenanthrenes, and their complexes w
ith amines have been synthesized. According to X-ray diffraction data,
the complex of diphenylphosphoryl-4H-1,3-dioxa-2-boraphenanthrene wit
h butylamine exists as a dimer due to the formation of intermolecular
hydrogen bonds.
