Notes:
High resolution proton decoupled 13C and 31P n.m.r. spectra of bis(diphenylphosphino)acetylene in (CD3)2SO and CDCl3 are analysed as ABX spectra to give the relative chemical shifts of the 13C and 31P nuclei as well as the spin-spin coupling constants 3J(PP) and nJ(PC). The differences in 31P shieldings are due to secondary 13C isotope effects which have been observed to be negligible over more than two bonds.
