Abstract
13 C and 1H N.m.r. spectra of But 2PPBut 2 at temperatures well below ambient show that there are two distinct environments for the tertiary butyl groups on the n.m.r. time-scale, whereas 31P spectra show there is only one type of phosphorus; this is attributed to the existence of the gauche isomer in preference to the trans and the two values of |1JPC+2JPPC| differ markedly.Keywords
