Rearrangement of O-benzoyl-N-(diphenylphosphinothioyl) hydroxylamine: An 18O-labelling investigation of oxygen-sulfur transposition

When Ph2P(S)NHOCOPh labelled with 18O 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 rearrange- meat (translation of O and S atoms) has all the label in the C=O group and none in the P=O group.

OPTICALLY ACTIVE SILYL ESTERS OF PHOSPHOROUS. II. STEREOCHEMISTRY OF REACTIONS WITH NUCLEOPHILES

We report the stereochemistry of reactions of various nucleophiles with optically active silyl esters of phosphorus of general formula: tBuPhP(X)OSiMePhNp X= -(1), Oxygen (2), Sulfur (3), Selenium (4).The list of nucleophiles includes O,S,N,C nucleophiles as well as halides.The nucleophilic attack is essentially directed towards silicon.The phosphinuos and phosphonic acid esters react with predominant retention of configuration at silicon atom, whereas the thiono and seleno crossover is explained in terms of possible interaction of the electrophilic part of the nucleophile with the oxyphosphoryl group or tricoordinate phosphorous.
