 Title    14N and 15N-NMR Spectroscopy of Diazaphospholes and the Linear Correlation of the Chemical Shift of Two-Coordinate N and P  
 Abstract    A systematic natural abundance 15N NM R study o f diazaphospholes is presented for the first tim e, giving accurate values for chemical shifts, 6 N , and coupling constants / (31P 15N), /(^ N 'H). 14N N M R spectra can be used to predict the magnitude o f '/ (31P 14N) if the broadening o f the 31P resonance by scalar relaxation is known. The relaxation behaviour o f the 14N nuclei corresponds to that found in azoles indicating a comparable electronic ground state structure. The com parison o f the chem ical shifts, <5N, in the diazaphospholes with (5N o f corresponding triazoles reveals differences which can be traced to the N —P cr-bonds and to the influence o f the phosphorus atom on the jr-system. A linear correlation (5N/<5P exists coordinate nitrogen and phosphorus, respectively.
