The material was recrystallized from 95% ethanol to yield undecane aldoxime (4.43 g, 41%, mp 69-7 1 "C (literature, 7 1-72 "C) (Lieberman 1955); IH NMR (CDC13): chemical shift (ppm), no. hydrogens, multiplicity, type; 0.9,3H, triplet, CH3; 1.2, 14 H, singlet, CH2; 1.4-1.6, 2H, multiplet, CH; 2.2, lH, m, CH; 2.4 , lH, multiplet, CH; 6.7, lH, broad singlet, OH; 7.4, lH, triplet, CH=N.…”

Synthesis of the first examples of 1H- and 4H-1,2,4,3λ3-triazaphospholes via unexpected ring-contraction reactions

“…(i) Addition of pinacol to (3b) or (3c), a reaction which is characteristic of cyclic two-co-ordinated phosphorus compounds ,2,6 gave rise, as expected, to the formation of the spirophosphorane In acetonitrile solution (12) is slowly converted into (13) at room temperature (3 days) by an unexpected ring contraction reaction involving an unusual cyclic phosphorus-carbon bond cleavage under very mild conditions. In this reaction (4) is trapped in its protonated form, the counter-anion being the (3H, d.JpH lOHz), 2.51 (3H, d,JpH lOHz), 4.0 (1H),4.4(1H,…”
