## Abstract Broad ^13^C resonances, as the result of partially relaxed scalar ^13^C^11^B coupling, were observed for the C‐1 and to a lesser extent C‐2 carbons of 1‐alkynyldioxaborolanes at 25°C. Measurement of the ^13^C spectra at 102°C resulted in a slower ^11^B quadrupolar relaxation rate and a

## Abstract ^13^C FT n.m.r. spectra were obtained from borates of methyl α‐D‐glucopyranoside, triethylboron, sodium tetraphenylboron and 1‐butaneboronic acid employing a simultaneous ^1^H and ^11^B decoupling network. The effectiveness of the system was evident using the three latter organoboron co

## Abstract Complete ^1^H, ^13^C, ^19^F and ^11^B NMR spectral data for 28 potassium organotrifluoroborates are described. The resonance for the carbon bearing the boron atom is described for most of the studied compounds. A modified ^11^B NMR pulse sequence was used and better resolution was obser
