When Ph2P(S)NHOCOPh labelled with O-18 in the C=O group (43% isotopic enrichment) reacts with NaOMe in MeOH the products are unlabelled Ph2P(O)NH2 and labelled PhCO2Me (43% isotopic enrichment). By implication, the intermediate Ph2P(O)NHSCOPh that results from rearrangement (transposition of O and S atoms) has all the label in the C=O group and none in the P=O group.
