Abstract

Scalar NMR spin–spin coupling constants across hydrogen bonds are fundamental in structural studies and as test grounds for theoretical calculations. Since they are scattered among many articles of different kinds, it seems useful to collect them in the most comprehensive way. Copyright © 2008 John Wiley & Sons, Ltd.

## Abstract The non‐classical 1,2‐diboretane‐3‐ylidene **1a** was studied by ^13^C and ^29^Si NMR spectroscopy in order to obtain coupling constants ^1^__J__(^13^C,^11^B) and ^1^__J__(^29^Si,^13^C). The magnitudes of ^1^__J__(^13^C,^11^B) were deduced from linewidth measurements in low‐temperature

lIf and 13C NMR contact shifts have been observed for chloroform, methylene cblorido and phenylacetylene in the presence of di-tertbutyl nitroxido radical (DBNO). Upfield and downfield contact shifts were observed for 1~ and 13f.2 NMR resonances, respectively. The relative values of 13C contact shif
