Boron Spirochelates Derived from Some Hydroxamic Acids and Carboxylic Acids

Das, M. K.,Chakraborty, S.

, p. 1123 - 1127 (2007/10/02)

A number of boron spirochelates of the general formula BY have been synthesized by the single-pot reaction of boric acid, a hydroxamic acid R'CON(R)OH and a carboxylic acid H2Y.The spirochelates have been characterized by elemental analyses, by IR, NMR (1H and 11B) and UV spectra and and conductance measurements.They are non-electrolytes.
