Popis:	The 31P spectra of H3PO3 + Ac2O and PCl3 + Ac2O contain signals which were assigned to the following compounds (δp, JpH): H3PO3(8,5; 702), AcO(OH)P(O)H (2,2; 739), (AcO)2P(O)H (-2,7; 763), (AcO)3P (131,6); PCl3 (220,7), AcOPCl2 (194,6), (AcO)2PCl (167,O), (AcOl3P (131,5). The active intermediates with -PH(O)Cl groups are formed on treating phosphorous PH-acids with AcCl, and in other reactions1. These intermediates are added to aldehydes and ketones resulting in compounds (I), (11) and (111). The compounds of type (11) treated with AcOH transform into compounds of different structure, e.g. into (IV) and (V).
