## Abstract The synthesis of 1‐fluoro‐4,4‐di‐hydroxymethyl‐pentane (I) and its dicarbamate (II) is described. (I) is obtained by classical alkylation of methylmalonic ester with 1‐ bromo‐3‐fluoro‐propane and subsequent reduction with LiAlH~4~, of the fluorinated diester obtained. Treated with phosg
3,3‐dimethylpentane‐2,4‐diol, a new diol, and its dicarbamate have been prepared. Some N,N‐diethylcarbamates of diols have also been prepared from N,N‐diethylcarbamoyl chloride and the corresponding diols.
Some new diethylcarbamates of dialkylamino‐alcohols of type I (fluorinated or not) have been prepared from diethylcarbamylchloride and the corresponding aminoalcohols.
## 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
