Abstract
2,2-N3P3(NH2)2Cl4 on complete alcoholysis in the NaOR/ROH system gave both rearranged 2,4-N3P3(NH2)2(OR)4 and unrearranged 2,2-N3P3(NH2)2(OR)4 (R = Me, CH2CF3), whilst for R = Et, Prn, Bun only the rearranged derivatives were observed. With NaOR in ether (R = Prn) only rearranged derivatives were obtained, whilst for R = CH2CF3, Ph only the unrearranged products were isolated. From the ROH/pyridine system only unrearranged derivatives (R = Me, Et, Prn, Pr1) were obtained. Partial alcoholysis studies suggested that the rearrangement occurred with the introduction of the second alkoxy group. The alcoholysis of 2,2-N4P4(NH2)2Cl6 and of 2,6-N4P4 (NH2)Cl6 using NaOR/ROH (R = Me) yielded 2,2-and 2,6-derivatives N4P4(NH2)2(OR)6 of the former and only the 2,6-isomers of the latter.
