Abstract: | Reactions of O‐aryl dihydrazinothiophosphinates ( 4, 5 ) or O,O′‐diarylhydrazinothio‐phosphonates ( 2 ) with glycosyl isocyanates ( 6 ) gave corresponding N‐(glycosylthioureylene)‐aminothiophosphonic and ‐diaminothiophosphinic O‐aryl esters. Their structures were confirmed by IR, 1H NMR, 31P NMR, MS and elemental analyses. |
