2-(Hydroxymethyl)pyridinium dihydrogenphosphate

Acta Crystallographica Section C Crystal Structure Communications, 2003
The title compound, C(6)H(8)NO(+).H(2)PO(4)(-), consists of 2-(hydroxymethyl)pyridinium and dihydrogenphosphate ions. The dihydrogenphosphate moieties are linked into chains by pairs of P-O-H.O-P hydrogen bonds. The 2-(hydroxymethyl)pyridinium cations are connected to the dihydrogenphosphate units by O-H.O and N-H.O hydrogen bonds.

Hydroxymethyl‐phosphine, Hydroxymethyl‐phosphoniumsalze und Chlormethyl‐phosphoniumsalze

Justus Liebigs Annalen der Chemie, 1962
AbstractHydroxymethylphosphine können durch Addition von Formaldehyd an primäre und sekundäre Phosphine oder durch alkalische Spaltung von Hydroxymethyl‐phosphoniumsalzen2) gewonnen werden. Beim Erhitzen unter vermindertem Druck destillieren sie teilweise unzersetzt, teilweise tritt Rückspaltung in die Komponenten oder Buckler‐Trippett‐Umlagerung zu ...

2‐(Hydroxymethyl)androstene Derivatives

Liebigs Annalen der Chemie, 1987
Abstract3‐Hydroxy‐2‐hydroxymethyl‐ (2 and 3) and 3‐hydroxymethyl‐3‐oxoandrostenes 4 were prepared from 2‐hydroxymethylene derivatives 1. The configurations of the chiral centers were determined on the basis of chiroptical, spectroscopical, and X‐ray analytical data. Furthermore, elimination reaction products (5, 6) were identified.
