Abstract : Variable temperature n.m.r. studies dimethylboric anhydride showed that the single boron-methyl resonance at tau 9.57 exhibited by this compound broadened as the temperature was lowered and split into two separate resonances below -- 68C. The activation energy for this phenomenon, calculated according to Gutowsky and Holm, is 8.6 kcal. The spectrum of the carbon analogue, di-isopropyl ether, remained unaffected as low as -- 100C.
