The addition of chloromethyl ethers (4a-c), (10a), and (11a) to 1-methoxy-2-methylprop-1-ene (5) is catalysed by mercury(II) chloride.Hydrolysis of the resulting chloro-ethers gives 3-alkoxy-2,2-dialkylpropanals which can be oxidised to the corresponding carboxylic acids with hydrogen peroxide in the presence of selenium dioxide as catalyst.Poly(alkoxyacetic) acids have been obtained by reaction of alkoxides with NN-dialkylchloroacetamides followed by hydrolysis.Thus the acids (12a-c) have been obtained from 2,2-dimethylpropane-1,3-diol, 2-hydroxymethyl-2-methylpropane-1,3-diol, and pentaerythritol, respectively.
