in tetrahydrofuran soln. of BH3*thf (120 mmol) in thf was added under N2 to 2,2'-o-phenylenedioxybis(1,3,2-benzodioxaborole) (120 mmol) which slowly dissolved on stirring; the react. was complete after 30 h (detected by (11)B-n.m.r. data);; the solvent was removed under vacuo (40-50 mm Hg) at ambient temp.; theconcd. soln. was then distd.;;

in diethylene glycol dimethyl ether (N2); soln. of Na(BH4) (34.1 mmol) in diglyme was added to the phenylene compd. (68.3 mmol) in diglyme; B2H6 carried away by an N2 stream, was absorbed in acetone; stirring overnight; (N2); distn. (80-100 °C, 100 mmHg) gave a soln. of the catecholatoborane (yield 97percent); the non-volatile residue dried (100 °C, 0.01 mmHg) and identfied as Na(B(O2C6H4)2) (11B NMR spectrum);
