✦ Synopsis


Abstract

Simple tertiary alcohols are dehydrated, and not phosphorylated, by polyphosphoric acid. However tertiary alcohols bearing a –COOR, or –CN, or –CONH~2~ group on the hydroxylated carbon are phosphorylated by this reagent to an extent of about 15%.

## Abstract Hydroxy nitriles when treated with polyphosphoric acid yield the corresponding carbamido‐alkyl phosphoric acids; but when treated with POCl~3~ in the presence of a tertiary base they yield the corresponding cyano‐alkyl phosphoric acids. β‐cyanoethyl phosphoric acid is very easily dephos

The authors describe modified procedures for the synthesis of phenylthiohydantoins derived from sr-amino acids, applied to 16 amino acids. With the exception of the phenylthiohydantoins containing a free -NH,, -CONH,, -COOH or heterocyclic group belonging to the starting amino acid, they can be puri

Menthol, unsaturated alcohols, and cyano alcohols are very easily esterified by phosphorous acid and yield the corresponding phosphorous monoesters. u-Cyano alcohols yield the corresponding carbamidoalkylphosphorous monoesters, whereas p, y , etc. cyano alcohols yield mixtures containing the corres
