Phosphorus–nitrogen compounds. Part 54. The reactions of geminal N3P3(NH2)2Cl4 and of N3P3(NH2)Cl5 with alkoxide ions in alcohols. The geminal P(NH2)2 to non-geminal P(NH2)(OR) rearrangement. The crystal structures of trans-N3P3(NH2)2(OPrn)4, cis-N3P3(NH2)2(OMe)4, and geminal N3P3(NH2)2(OMe)4
Abstract
Geminal N3P3(NH2)2Cl4 has been allowed to react with alkoxide ions in alcohol to give rearranged cis- and trans-N3P3(NH2)2(OR)4(R = Me, Et, Prn, or Bun), as well as unrearranged geminal N3P3(NH2)2(OR)4(R = Me). The 1H, 13C, and 31P n.m.r. spectra are reported. The crystal structures of trans-N3P3(NH2)2(OPrn)4, geminal and cis-N3P3(NH2)2(OMe)4 are presented, the last two being present in a 1 : 1 ratio in the same unit cell.
